Was Jesus a white man or a black man?

We must not think about Jesus Christ as an ordinary human being. We must remember that he was God who became man in order to save sinful humanity from everlasting doom. Long before he became man he existed in heaven as God (John 1:1). John speaks about him as "the Word". We must further remember that He was not born out of the seed of a man, but by a miracle worked by the Holy Spirit (Luke 1 and 2). He became man for very specific reasons (Phillipians 2:6-8):

1. To seek and to save what is lost (Luke 2:11; Luke 19:10; John 3:17; 1 Timothy 1:15; Hebrews 7:25).

2. To carry the burden of our sins (Isaiah 53:5; 1 Peter 2:24; Hebrews 9:28).

3. To become the Mediator between us all and God (1 Timothy 2:5; Hebrews 8:6; Hebrews 9:15,24 and 1 John 1:2).

4. To sacrifice himself and to die for us (Romans 5:6; Revelation 5:9).

He did this for all people of all races and languages and nations (Revelation 5:9). The colour of his human skin has nothing to do with it. Humanly speaking, we believe that his human body probably had the colour of the Jews whom you still find in Israel today. Some of them are darker than others.
