Timbuk 3’s one hit wonder from the 80s, The Future’s So Bright, I Gotta Wear Shades comes to mind when reading John 8:12.
12 Again Jesus spoke to them, saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.”(ESV)
As he passed by, he saw a man blind from birth. 2 And his disciples asked him, “Rabbi, who sinned,this man or his parents, that he was born blind?” 3 Jesus answered, “It was not that this man sinned, or his parents, but that the works of God might be displayed in him. 4 We must work the works of him who sent me while it is day; night is coming, when no one can work. 5 As long as I am in the world, I am the light of the world.”(ESV)
9 Jesus answered, “Are there not twelve hours in the day? If anyone walks in the day, he does not stumble, because he sees the light of this world. 10 But if anyone walks in the night, he stumbles, because the light is not in him.”(ESV)
35 So Jesus said to them, “The light is among you for a little while longer. Walk while you have the light, lest darkness overtake you. The one who walks in the darkness does not know where he is going. 36 While you have the light, believe in the light, that you may become sons of light.”(ESV)
15 And I said, ‘Who are you, Lord?’ And the Lord said, ‘I am Jesus whom you are persecuting. 16 But rise and stand upon your feet, for I have appeared to you for this purpose, to appoint you as a servant and witness to the things in which you have seen me and to those in which I will appear to you, 17 delivering you from your people and from the Gentiles—to whom I am sending you 18 to open their eyes, so that they may turn from darkness to light and from the power of Satan to God, that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.’(ESV)
Jesus is the light of the world, if you walk with Him, you will never walk in darkness. Trouble is the majority of people are not walking with Jesus, they are walking in darkness.
