Yup. What they look like today. However, @Who-me brought up an excellent point. What He looked like then is not what He looks like today. He came in as a lamb, yet He will come back a lion and a conquering King. My first answer was this.
“He had no beauty or majesty to attract us to him, nothing in his appearance that we should desire him.” Isaiah 53:2
He blended into a crowd: Jesus looked like an ordinary first-century Jewish man from Galilee. When Judas betrayed him in the Garden of Gethsemane, he had to give the soldiers a specific sign (a kiss) because they couldn’t visually distinguish Jesus from his disciples on their own.
As a first-century Middle Eastern man who worked as a tekton, a builder or stone-cutter, until he was 30, Jesus would have been deeply tanned from the sun, physically weathered, with dark, short hair and a beard, typical of Jewish men of that era. While Jesus chose to conceal his heavenly glory during most of his earthly ministry, there was one moment when he pulled back the veil. On the Mount of Transfiguration, Peter, James, and John got a glimpse of his true nature:
“There he was transfigured before them. His face shone like the sun, and his clothes became as white as the light.” Matthew 17:2
In this moment, his appearance wasn’t defined by skin or hair color, but by pure, unapproachable light. Then you have His return.
“The hair on his head was white like wool, as white as snow, and his eyes were like blazing fire. His feet were like bronze glowing in a furnace, and his voice was like the sound of rushing waters. In his right hand, he held seven stars, and coming out of his mouth was a sharp, double-edged sword. His face was like the sun shining in all its brilliance.” Revelation 1:14-16
However, as many have said here, it really does not matter. Will you go to heaven and see a black Jesus, a blue-eyed blonde Jesus, or a Jew, and say, "Oh, I’m sorry, you do not look like I thought, so I will not enter? I would hope not.
Peter
