Living Preface of God - Isaiah 1:1-20

1.1 We are at the beginning of a new year. Usually, this is the time when we make new schedules and resolutions. Some of us decide to start a diet, while others plan to study harder. Churches are no exception. We often spend this time creating plans, programs, and events to promote spiritual growth. As a pastor, I am always looking for better ways to strengthen our spiritual lives. However, I’ve noticed a danger: when programs become the main focus, we can easily lose sight of God’s vision. Instead of experiencing God, we simply focus on completing the tasks. I call these 'empty events.' As followers of Christ, we must be careful to avoid this trap of 'empty' religion.

1.2 This year, we are beginning a journey through the Book of Isaiah. I chose this book because it teaches us how to keep our faith sincere and apply God’s Word to our real lives. With the help of the Spirit, Isaiah will help us discern the difference between true devotion and busy church work. Let us now turn our hearts to God’s Word in Isaiah 1:12-20.

Isaiah 1:12–15 NLT

When you come to worship me, who asked you to parade through my courts with all your ceremony? Stop bringing me your meaningless gifts; the incense of your offerings disgusts me! As for your celebrations of the new moon and the Sabbath and your special days for fasting— they are all sinful and false.
I want no more of your pious meetings. I hate your new moon celebrations and your annual festivals. They are a burden to me. I cannot stand them! When you lift up your hands in prayer, I will not look. Though you offer many prayers, I will not listen, for your hands are covered with the blood of innocent victims. 

Isaiah 1:16–20 NLT

Wash yourselves and be clean! Get your sins out of my sight. Give up your evil ways. Learn to do good. Seek justice. Help the oppressed. Defend the cause of orphans. Fight for the rights of widows. “Come now, let’s settle this,” says the Lord. “Though your sins are like scarlet, I will make them as white as snow.
Though they are red like crimson, I will make them as white as wool. If you will only obey me, you will have plenty to eat. But if you turn away and refuse to listen, you will be devoured by the sword of your enemies. I, the Lord, have spoken!” 

Introduction: The Crisis of "Busy Religion"

2.1 Isaiah starts by setting a scene, but it’s not a typical scene. It is like a courtroom drama, but with a heart-breaking twist. In Hebrew, this is called a 'Rîb'—a covenant lawsuit. In this cosmic trial, God summons the heavens and the earth to be his witnesses. But we need to look closely at the Judge. God is not just a distant King or a cold Lawmaker. He is a Father bringing a case against His own children. Imagine the pain of a parent whose children have turned their backs on everything they were taught. God says in verse 2, "I reared and brought up children, but they have rebelled against me." This isn't just a legal issue; it’s a relational tragedy.

Isaiah 1:2 ESV

Hear, O heavens, and give ear, O earth; for the Lord has spoken: “Children have I reared and brought up, but they have rebelled against me. 

2.2 Here, we see a shocking paradox. At this time, the people of Judah were incredibly "religiously busy." If you looked at their church calendar, it was full. They were parading through the temple courts, offering many sacrifices, burning incense, and celebrating every festival. On the outside, they looked like the most devoted believers. But in God's eyes, they were "spiritually bankrupt." Their busy schedules were not a sign of life, but a way to cover up their spiritual death. This leads us to a very deep and challenging question for our new year: Is our church activity a bridge to God, or a mask to hide from Him? Sometimes, we use our busy-ness in the church to make ourselves feel better, while our hearts stay far away from God’s true character. God’s response to this kind of "empty religion" is surprisingly strong. He doesn't just ignore it; He says it disgusts Him. Let’s look at why God feels this way. Even Jesus warned the religious leaders. 

Matthew 23:23–24 NASB 2020

“Woe to you, scribes and Pharisees, hypocrites! For you tithe mint and dill and cumin, and have neglected the weightier provisions of the Law: justice and mercy and faithfulness; but these are the things you should have done without neglecting the others. You blind guides, who strain out a gnat and swallow a camel! 

2.3 This leads us to a very deep and challenging question for our new year: Is our church activity a bridge to God, or a mask to hide from Him? Sometimes, we use our busy-ness in the church to make ourselves feel better, while our hearts stay far away from God’s true character. God’s response to this kind of "empty religion" is surprisingly strong. He doesn't just ignore it; He says it disgusts Him. Let’s look at why God feels this way.

The Divine Disgust: When Worship Becomes "Trampling" (vv. 10-15)

3.1 The Shocking Address (v. 10): As we look at verse 10, Isaiah delivers a message that must have been a huge shock to the listeners. God addresses the leaders and the people as "Rulers of Sodom" and "People of Gomorrah." To a Jewish person, these cities were the ultimate symbols of wickedness and judgment. Imagine the reaction! These were people who thought they were holy because they were in the temple, yet God calls them the moral equivalent of Sodom. This tells us a hard truth: Religious success can actually be a mask for moral failure. They were excellent at ceremonies, but they had failed in their character.

3.2 The Evidence: "Full Hands" (v. 15): The most powerful and painful image in this passage is found in verse 15. The people are standing in prayer, lifting their hands toward heaven—a posture of worship and surrender. But God says, "I will hide my eyes... I will not listen." Why? Because when God looks at their raised hands, He doesn't see holy hands; He sees hands "covered with the blood of innocent victims." This blood represents the social injustice they allowed—the poor who were ignored, the widows who were cheated, and the orphans who were oppressed. Their "pious" hands in the temple were the same hands that hurt others during the week.

3.3 The Warning for Today's Church:  God’s words here are a serious warning for our modern church life. He points out three dangerous gaps:

• Sacrifices without Sacrifice (v. 11): They gave many animals, but they didn't give their hearts. They gave "stuff" to God to avoid giving "themselves."

Isaiah 1:11 NKJV

“To what purpose is the multitude of your sacrifices to Me?” Says the Lord. “I have had enough of burnt offerings of rams And the fat of fed cattle. I do not delight in the blood of bulls, Or of lambs or goats.

• Attendance without Presence (v. 12): God describes their coming to the temple as "parading" or "trampling" His courts. It was just a habit, like a crowd walking through a stadium, with no real meeting with the Living God.

Isaiah 1:12 NIV

When you come to appear before me, who has asked this of you, this trampling of my courts? 

• Prayers without Justice (v. 15): They offered many prayers, but God could not hear them because they ignored the cries of the suffering.

Isaiah 1:15 MSG

When you put on your next prayer-performance, I’ll be looking the other way. No matter how long or loud or often you pray, I’ll not be listening. And do you know why? Because you’ve been tearing people to pieces, and your hands are bloody.

3.4 The Core Issue: Religion as a Defense Mechanism This brings us to the core issue. Religion becomes a "defense mechanism" against God when it doesn't transform how we treat others. We often use religious activities to feel safe from God’s demands. We think, "If I attend this meeting or finish this program, I have done my duty." But true worship is not a performance to please a distant King; it is a lifestyle that reflects God’s heart. If our worship on Sunday doesn't change how we treat people on Monday, God calls it a "burden" that He cannot stand. At this point, we should remember why Jesus came to us and how He began His work. Luke understood very clearly why Jesus was here.

Luke 4:18–19 GNB

“The Spirit of the Lord is upon me, because he has chosen me to bring good news to the poor. He has sent me to proclaim liberty to the captives and recovery of sight to the blind; to set free the oppressed and announce that the time has come when the Lord will save his people.” 

3.5 Jesus didn't come just to perform religious rituals or to start a new religion or church. Instead, He came to fulfill God’s promises and to show us what God is really like. Through His actions, Jesus became the perfect example for how we should live our lives.

The True Direction: Reflecting God's Character (vv. 16-17)

4.1 From Stopping to Starting: The Nine Imperatives (vv. 16-17): After showing us the problem of "empty religion," God doesn't just leave us there. In verses 16 and 17, He gives us a clear path forward through seven powerful commands. It starts with cleaning up: "Wash yourselves... get your sins out of my sight." But the most important part is the transition. God moves from telling us what to stop to telling us what to start. He says, "Cease to do evil," but immediately follows it with, "Learn to do good." This is a key point: doing good is not something that happens naturally. It is a skill we must "learn" and practice every day with the help of the Holy Spirit.

Isaiah 1:16–17 ESV

1) Wash yourselves; make yourselves clean; 2) remove the evil of your deeds from before my eyes; 3) cease to do evil, 4) learn to do good; seek justice, 5) correct oppression;  bring justice to the fatherless, 6) plead the widow’s cause. 

4.2 The Church’s True Liturgy (v. 17): We often think of "liturgy" as the order of our service—the songs, the prayers, and the sermon. But Isaiah shows us the church’s "true liturgy" happens outside the temple walls. God defines worship by how we treat the most vulnerable people in our society. He says: "Seek justice. Help the oppressed. Defend the cause of orphans. Fight for the rights of widows." In Isaiah’s time, orphans and widows had no social power and no one to protect them. Today, God is still asking us: Who are the "orphans and widows" in our community? True worship is not about how loud we sing, but how much we care for those who have no voice.

4.3 The Character of the "Holy One of Israel": Why does God care so much about justice? It is because of His very nature. Throughout this book, Isaiah calls God "The Holy One of Israel." This title tells us two things. First, God is "Holy"—He is set apart, morally pure, and completely different from our world. Second, He is the God "of Israel"—He is deeply committed and connected to His people. Because God is holy and committed to us, we who are called by His name must also be "set apart" from the world's selfishness and "committed" to the world’s healing.

Leviticus 11:44–45 ESV

For I am the Lord your God. Consecrate yourselves therefore, and be holy, for I am holy. You shall not defile yourselves with any swarming thing that crawls on the ground. For I am the Lord who brought you up out of the land of Egypt to be your God. You shall therefore be holy, for I am holy.” 

4.4 Application: Mišpāṭ as the Practice of the GospelOur yearly plans and programs must be more than just "church work." They must be the practice of Mišpāṭ, which is the biblical word for justice. I like to call this the "alchemical practice" of the Gospel. In history, alchemy was the attempt to turn common metals into gold. In a spiritual sense, when we take our ordinary church activities and use them to seek justice and help the oppressed, we are turning "religion" into something divine. We are showing the world the true character of God. As one scholar said, "Justice is the ultimate test of worship." If we want to know if our worship is real, we just need to look at how we treat the people around us.

The Gospel Offer: Forensic Grace (vv. 18-20)

5.1 The "Scarlet" Solution: The Need for a Miracle (v. 18): In verse 18, God says something amazing: "Come now, let’s settle this." Even though He is the Judge and we are the guilty ones, He invites us to a conversation. He knows our hands are dirty and covered in "blood." But here is the problem: we cannot wash ourselves clean through our own effort. Isaiah uses the words "scarlet" and "crimson." In the ancient world, these were permanent dyes. Once a cloth was stained with these colors, it was impossible to make it white again. This shows us that sin is not just a small mistake we can fix; it is a deep, permanent stain on our souls. We need more than a "program"; we need the "alchemical miracle" of God’s grace—a power that can do what is humanly impossible.

5.2 White as Snow: A Forensic Transformation (v. 18): God promises, "I will make them as white as snow... as white as wool." This is what we call a "forensic transformation." It means that God, the Righteous Judge, doesn't just "look the other way" or ignore the blood on our hands. Instead, through His grace, He actually cleanses us. He changes our spiritual identity from "guilty" to "innocent." This grace doesn't just cover our sins; it removes the stain. It transforms our "hands of blood" into "hands of service." This is the heart of the Gospel: we are made clean not by our religious works, but by the miraculous work of God.

Job 23:10 ESV

But he knows the way that I take; when he has tried me, I shall come out as gold. 

5.3 The Binary Choice: Eat or Be Eaten (vv. 19-20): The lawsuit concludes with a very clear, binary choice. Isaiah uses a powerful wordplay with the As we reach the end of this divine lawsuit, God presents us with a very clear choice. Isaiah uses a powerful play on words with the Hebrew verb "to eat" to show us what is at stake. First, there is the path of Willing Obedience. If we truly accept God's grace and begin to practice justice and mercy in our daily lives, God promises that we will "eat the good of the land." This is a beautiful picture of covenant blessing—a life that is nourished and satisfied by the goodness of God. It means our souls will be full because we are living in a right relationship with Him and our neighbors. However, there is another path: Continued Rebellion. If we choose to turn away, refusing to listen and staying stuck in our "empty rituals," the warning is sobering. God says we will be "eaten by the sword." The message is stark: either we consume the blessings of God's grace, or we are consumed by the consequences of rejecting Him. There is no middle ground. As we start this new year, the choice is ours—will we be a community that truly "eats" the goodness of God’s Kingdom, or will we let our empty religion lead us to destruction?

5.4 As you know, I have been studying the Swiss Reformation. I have been looking specifically at the meaning of Baptism, the Lord’s Supper, and how the Church and the State should relate to each other. Last week, while writing the sixth chapter of my dissertation, I spent a lot of time thinking about a very important balance.

A church that only focuses on being pure but ignores the needs of the community is like a clinic without any patients. On the other hand, a church that is very active in the world but loses its spiritual holiness is like medicine without a doctor.

I believe the right path forward is to keep our values separate from worldly politics, while staying fully committed to serving the world. If the church loses its roots—which is our Lord Jesus Christ and our faith in Him—it becomes just an empty religion. But if the church focuses only on its own human desires, it will end up teaching nothing more than moral rules. We must not neglect any part of what God has given us.

Conclusion: The Church as the Living Preface

6.1 The Living Preface: In the world of books, a "preface" is the introduction that explains the heart of the whole story. Biblical scholars often call Isaiah chapter 1 the "Preface" to the entire book of Isaiah. It shows us the deep problem of our sin, but it also reveals the beautiful solution of God’s grace. As we start this new year, I want to challenge us with this: The life of our church should be a "Living Preface" to the Gospel for our community. When people look at us, they should be able to read a summary of who God is. They shouldn't just see a group of people busy with religious events; they should see a community that reflects the "Fatherly Heart" of God.

6.2 The Balance of Faith and Action: As I’ve been studying the Swiss Reformation, I am reminded that we cannot choose between spiritual purity and social action. We need both. A church without a deep root in Jesus Christ is just an empty social club. But a church that stays only inside its own walls is like medicine that never reaches the sick. Our goal for 2026 is to be a church that is "set apart" in our faith, but "fully committed" in our service. We want our liturgy on Sunday to fuel our justice on Monday. We want our prayers to lead us to the oppressed, the lonely, and the broken-hearted in our city.

6.3 Call to Action: Worship in the Real World: So, let us go into this week with a new vision. Let’s not just "do" church; let’s "be" the church. I want to give you a small but powerful challenge for this first week of the year: Find one person to whom you can show God’s justice and mercy. Maybe it is defending someone who is being treated unfairly, or helping someone who is struggling alone. When you seek justice for that one person, you are performing the truest form of worship. You are showing the world that our God is not just a Judge in a courtroom, but a Father who loves His children and wants them to come home. Let our lives be the "Living Preface" that invites the world to meet the Holy One of Israel. Though our sins were like scarlet, we have been made white as snow. Now, let us live as those who have been washed by grace.

--------------------------------------------------------------------------------

Answer Key

1. The primary danger is that church programs, plans, and events can become the main focus, leading to "empty events" where people focus on completing tasks rather than experiencing God. This can cause the church to lose sight of God's vision and fall into the trap of "empty" religion.

2. A ‘Rîb’ is a Hebrew term for a covenant lawsuit. This frames the scene in Isaiah 1 not just as a legal trial, but as a relational tragedy where God is a heartbroken Father bringing a case against His own rebellious children.

3. The paradox was that the people of Judah were incredibly "religiously busy," with full calendars of sacrifices, festivals, and temple worship. However, in God's eyes, this activity masked the fact that they were "spiritually bankrupt" and their hearts were far from Him.

4. To a Jewish person, Sodom and Gomorrah were the ultimate symbols of wickedness and divine judgment. By using these titles, God revealed that their outward religious success was a mask for profound moral failure, placing them in the same category as the most wicked cities.

5. The image of bloody hands represents the pervasive social injustice they allowed and participated in. While they lifted "pious" hands in prayer, those same hands were metaphorically stained with the suffering of the poor, cheated widows, and oppressed orphans they harmed during the week.

6. The "church's true liturgy" happens outside the temple walls, in the real world. It involves reflecting God's character by actively carrying out His commands to "seek justice, help the oppressed, defend the cause of orphans, and fight for the rights of widows."

7. A "forensic transformation" means that God, as the Righteous Judge, does not simply ignore sin but actively cleanses it. He changes a person's spiritual identity from "guilty" to "innocent," removing the permanent stain of sin just as He promises to make scarlet sins "white as snow."

8. The binary choice is between willing obedience and continued rebellion. Using a play on the Hebrew verb "to eat," God promises that the obedient will "eat the good of the land," while the rebellious will be "eaten by the sword."

9. The first analogy is a church that is pure but ignores the community, which is like a "clinic without any patients." The second is a church that is socially active but loses its spiritual holiness, which is like "medicine without a doctor."

10. To be a "Living Preface" means the church's collective life should serve as an introduction to the story of the Gospel for the surrounding community. People should be able to look at the church and see a summary of God's character, particularly His fatherly heart and His commitment to justice and mercy.
