In this lesson, students learn how to worship the LORD.
Devotion
Now, in the Old Testament, God separated the seventh day, and appointed it for rest, and commanded that it should be regarded as holy above all others. As regards this external observance, this commandment was given to the Jews alone, that they should abstain from toilsome work, and rest, so that both man and beast might recuperate, and not be weakened by unremitting labor.
This commandment, therefore, according to its gross sense, does not concern us Christians; for it is altogether an external matter, like other ordinances of the Old Testament, which were attached to particular customs, persons, times, and places, and now have been made free through Christ.
But to grasp a Christian meaning for the simple as to what God requires in this commandment, note that we keep holy days not for the sake of intelligent and learned Christians (for they have no need of it [holy days]), but first of all for bodily causes and necessities, which nature teaches and requires; for the common people, man-servants and maid-servants, who have been attending to their work and trade the whole week, that for a day they may retire in order to rest and be refreshed.
Secondly, and most especially, that on such day of rest (since we can get no other opportunity) freedom and time be taken to attend divine service, so that we come together to hear and treat of God's and then to praise God, to sing and pray.
Accordingly, when asked, What is meant by the commandment: Thou shalt sanctify the holy day? answer: To sanctify the holy day is the same as to keep it holy. But what is meant by keeping it holy? Nothing else than to be occupied in holy words, works, and life. For the day needs no sanctification for itself; for in itself it has been created holy [from the beginning of the creation it was sanctified by its Creator]. But God desires it to be holy to you. Therefore it becomes holy or unholy on your account, according as you are occupied on the same with things that are holy or unholy.
How, then, does such sanctification take place? Not in this manner, that [with folded hands] we sit behind the stove and do no rough [external] work, or deck ourselves with a wreath and put on our best clothes, but (as has been said) that we occupy ourselves with God's Word, and exercise ourselves therein.
And, indeed, we Christians ought always to keep such a holy day, and be occupied with nothing but holy things, i.e., daily be engaged upon God's Word, and carry it in our hearts and upon our lips. But (as has been said) since we do not at all times have leisure, we must devote several hours a week for the sake of the young, or at least a day for the sake of the entire multitude, to being concerned about this alone, and especially urge the Ten Commandments, the Creed, and the Lord's Prayer, and thus direct our whole life and being according to God's Word. At whatever time, then, this is being observed and practised, there a true holy day is being kept; otherwise it shall not be called a Christians' holy day. For, indeed, non-Christians can also cease from work and be idle, just as the entire swarm of our ecclesiastics, who stand daily in the churches, singing, and ringing bells but keeping no holy day holy, because they neither preach nor practises God's Word, but teach and live contrary to it.
The lesson
26 Later a son was born to Seth, and he named him Enosh. This is when people began to proclaim[a] the name of the Lord. ( Enosh means to call upon.)
41 Every year his parents traveled to Jerusalem for the Passover Festival. 42 When he was twelve years old, they went up according to the custom of the Festival. 43 When the days had ended, as they were returning, the boy Jesus stayed behind in Jerusalem. His parents did not know it. 44 Since they thought he was in their group, they went a day’s journey. Then they began to look for him among their relatives and friends. 45 When they did not find him, they returned to Jerusalem, searching for him.
46 After three days they found him in the temple courts, sitting among the teachers, listening to them and asking them questions. 47 And all who heard him were amazed at his understanding and his answers. 48 When his parents saw him, they were astonished. His mother said to him, “Son, why have you treated us this way? See, your father and I have been anxiously looking for you.”
49 He said to them, “Why were you looking for me? Did you not know that I must be taking care of my Father’s business?” 50 They did not understand what he was telling them.
51 He went down with them and came to Nazareth. He was always obedient to them. And his mother treasured up all these things in her heart. 52 Jesus grew in wisdom and stature, and in favor with God and with people.
