"Light of the World" (Greek: φώς τοῦ κόσμου Phṓs tou kósmou) is a phrase used by Jesus to describe himself and his disciples in the New Testament.
It is closely related to the parables of salt and light and lamp under a bushel, which also appear in Jesus' Sermon on the Mount.
In John 8:12 Jesus applies the title to himself while debating with the Jews and states:[1] I am the light of the world.
Whoever follows me will never walk in darkness, but will have the light of life.Jesus again claims to be Light of the World in John 9:5, during the miracle of healing the blind at birth, saying: [2] This episode leads into John 9:39 where Jesus metaphorically explains that he came to this world, so that the blind may see.
"[3] These assertions build on the Christological theme of John 5:26 where Jesus claims to possess life just as the Father does and provide it to those who follow him.
