Had a discussion with a friend and he asked "Do we really know what Jesus looked like? How tall was he? Color of hair, etc..? Do the paintings really portray the accuracy?" The best answer I could find was here.. Any thoughts? Outside of Scripture, it's only speculation.
"As many were astonished at you—
his appearance was so marred, beyond human semblance,
and his form beyond that of the children of mankind"
-Isaiah 52:14
If you recall Athens was a Greek city which Paul said was "wholly given over to idolatry".
The Bible is full of condemnation, both old and new testaments, for those who make idols, or engage in any kind of idolatry.
As we know, all sin is born first in the mind, then flows outward... Jesus is very adamant about that to the point of condemning even thoughts as sin.
An interesting occurance happened with Jesus during His life. Some Greeks (coming from a country given over to idols) went to Phillip, and asked if they could please "see" (a Hebrew word which means "to perceive with the eyes") Jesus. (John 12:20-21)
So when Jesus was told of this request, His response was to "see" him by faith, as shown in the following response:
John 12:23 “And Jesus answered them, saying, The hour is come, that the Son of man should be glorified. Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit. He that loveth his life shall lose it; and he that hateth his life in this world shall keep it unto life eternal. If any man serve me, let him follow me; and where I am, there shall also my servant be: if any man serve me, him will my Father honour. Now is my soul troubled; and what shall I say? Father, save me from this hour: but for this cause came I unto this hour. Father, glorify thy name. Then came there a voice from heaven, saying, I have both glorified it, and will glorify it again. The people therefore, that stood by, and heard it, said that it thundered: others said, an angel spake to him. Jesus answered and said, this voice came not because of me, but for your sakes. Now is the judgment of this world: now shall the prince of this world be cast out. And I, if I be lifted up from the earth, will draw all men unto me. This he said, signifying what death he should die.”
We Glorify HIM not by imagining Him in human form, but rather, by seeing Him for what He truly is, and we see that not through imaginings of a human form, but rather we have sight by faith and serve Him in this capacity.
