When Jesus spoke again to the people, he said, "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life." John 8:12
Yes! “In him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it. There came a man who was sent from God; his name was John. He came as a witness to testify concerning that light, so that through him all men might believe. He himself was not the light; he came only as a witness to the light. The true light that gives light to every man was coming into the world.” John 1:4-9
“This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God." John 3:19-21
“For God, who said, "Let light shine out of darkness," made his light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ.” 2 Corinthians 4:6 (NIV) “The LORD is my light and my salvation-- whom shall I fear? The LORD is the stronghold of my life-- of whom shall I be afraid?” Psalms 27:1 “Send forth your light and your truth, let them guide me; let them bring me to your holy mountain, to the place where you dwell.”Psalms 43:3
“For you were once darkness, but now you are light in the Lord. Live as children of light (for the fruit of the light consists in all goodness, righteousness and truth) and find out what pleases the Lord. Have nothing to do with the fruitless deeds of darkness, but rather expose them. For it is shameful even to mention what the disobedient do in secret. But everything exposed by the light becomes visible, for it is light that makes everything visible. This is why it is said: "Wake up, O sleeper, rise from the dead, and Christ will shine on you." Ephesians 5:8-14 (From NIV)
