I am the light of the world:

John 8:12
“Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.”

King James Version (KJV)

John 8:12 Context

9And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst. 10When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee? 11She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more. 12Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life. 13The Pharisees therefore said unto him, Thou bearest record of thyself; thy record is not true. 14Jesus answered and said unto them, Though I bear record of myself, yet my record is true: for I know whence I came, and whither I go; but ye cannot tell whence I come, and whither I go. 15Ye judge after the flesh; I judge no man.
