“No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him” (John 1:18).
To see God, we must believe in his only begotten Son.
“For there is one God, and one mediator between God and men, the man Christ Jesus: who gave himself a ransom for all, to be testified in due time” (1 Timothy 2:5–6).
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.” (John 3:16, 18).
“Who is he that overcometh the world, but he that believeth that Jesus is the Son of God? This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth” (1 John 5:5–6).
Jesus Christ says: “God is a Spirit: and they that worship him must worship him in spirit and in truth. But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him” (John 4:24, 23).
