Contradiction with John 1:18
This verse states that no one has seen God at any time, which contradicts John 14:7, where knowing Jesus is equated with knowing the Father.
John 1:18: No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared [him].
Contradiction with 1 Timothy 6:16
It declares that God dwells in unapproachable light and no one has seen or can see Him, contradicting Jesus' claim in John 14:7 of knowing the Father through knowing Him.
1 Timothy 6:16: Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom [be] honour and power everlasting. Amen.
Contradiction with Exodus 33:20
Here God tells Moses that no one can see Him and live, contradicting Jesus' implication in John 14:7 that seeing Him is seeing the Father.
Exodus 33:20: And he said, Thou canst not see my face: for there shall no man see me, and live.
