For starters, have a good look at John 1:
[my addition]
1 In the beginning [Lit: Before time/ before the begging] was the Word, and the Word was with God,
and the Word was God.
2 He was with God in the beginning.
3 Through him
all things were made; without him nothing was made that has been made.
4 In him was life, and that life was the
light of all mankind.
5 The
light shines in the darkness, and the darkness has not overcome[SUP]
a[/SUP] it.
6 There was a man sent from God whose name was John.
7 He came as a witness to testify concerning that light, so that through him all might believe.
8 He himself was not the light; he came only as a witness to the light.
9 The
true light [Jesus] that gives light to everyone was coming into the world.
10 He was in the world, and though the world was made through him, the world did not recognize him.
11He came to that which was his own, but his own did not receive him.
12 Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God—
13 children born not of natural descent, nor of human decision or a husband’s will, but born of God.
14 The Word [Jesus] became flesh and made his dwelling among us . We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth

John 8:12 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."
