Jesus is not a metaphor for the sun. Sun worship is prohibited in the Bible.
John 8:12 When Jesus spoke again to the people, he said, "I am the light of the world." (The "light of the world" is the Sun.)
John 9:5 While I am in the world, I am the light of the world. (The "light of the world" is the Sun.)
Matthew 4:16 The people living in darkness have seen a great
light; on those living in the land of the shadow of death a
light has dawned." (The
light is the
Sun)
Matthew 17:2 His face shone like
the sun, and
his clothes became as white as
the light.
John 1:3-8 Through him all things were made; without him nothing was made that has been made. (Without the Sun nothing would grow and we'd all be dead.) In him was life, and that life was the
light of men. (The
light is the Sun.) The
light shines in the darkness, and the darkness has not overcome it (the Sun removes the darkness). There came a man who was sent from God; his name was John. He [John] came as a witness to testify concerning that
light(the Sun), so that through him all men might believe. He [John] himself was not the
light; he came only as a witness to the
light. The true
light (the Sun) that gives
light to every man was coming into the world.
John 3:19-20 This is the verdict:
Light(the Sun) has come into the world, but men loved darkness (night time) instead of
light (the Sun) because their deeds were evil (criminals do their crimes at night). Everyone who does evil hates the
light (the Sun), and will not come into the
light (the Sun) for fear that his deeds will be exposed.
John 12:35-36 Then Jesus told them, "You are going to have
the light (
the light is
the Sun) just a little while longer (the Sun will set soon). Walk while you have
the light (
the light is
the Sun), before darkness (night time) overtakes you. The man who walks in the dark (at night) does not know where he is going. Put your trust in
the light (
the light is
the Sun) while you have it, so that you may become sons of light." When he had finished speaking, Jesus left and hid himself from them (i.e. the sun set, because Jesus is the Sun).
John 12:46 I have come into the world as a
light (the Sun), so that no one who believes in me should stay in darkness.
Ephesians 5:14 Christ (the Sun) will
shine on you.
Philippians 3:20 For our conversation is in heaven (the celestial sphere above); from whence also we look for the Saviour, the Lord Jesus Christ (the Sun). (i.e. we should look upwards to the celestial sphere above to find our story.)
Colossians 3:2 Set your minds on things
above, not on earthly things.
Luke 4:19 To preach the acceptable year of the Lord. (i.e. the story is about the passage of the year.)
Psalms 84:11 "the Lord God is a sun..."
Deuteronomy 4:24 "For the LORD your God is a consuming fire," (the Sun is a consuming fire.)
Malachi 4:2 "But unto you that fear my name shall the Sun of righteousness arise with healing in his wings..."
