God is invisible, Jesus is not invisible. Your John 1:18 translation is bunk and contradicts Scripture. Means Jesus is not God because the ONLY GOD is invisible.
Colossians 1
15Who is the
image of the invisible God, the firstborn of every creature:
1 Timothy 1
17Now to the King eternal, immortal, and
invisible, the only God, be honor and glory forever and ever. Amen.
This is the correct version because the only God is invisible, but many saw Jesus, contrary to your version saying that Jesus is God. John 1 is a travesty for trintiarianism.
John 1 (NKJV)
18No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared
Him.
