Perhaps one of the reasons man has failed to ignore color, is his failure to believe the Bible, to take it as God's Word. Even with a child's simple understanding of Scripture, one knows that every human being came from a single human being, created by God, out of the dust of the ground (Gen. 2:7). From the first man, Adam, God removed a rib and created for him, a mate, Eve (Gen. 2:20-25). This sounded ridiculous to those who reject the Bible as historically true, until man discovered a way to clone living things. And how difficult would it be for God to simply add a fourth "leg" to Adam's XY chromosomes, making Eve's genetic make-up of XX?
Adam "knew" Eve, apparently several times, and Eve bore children, lots and lots of children. By the time a man named Noah was born (the tenth generation from Adam), the world was pretty well populated. God described its population as being wicked continuously (Gen. 6:5-7). So, He destroyed the entire planet by flooding it to a level of fifteen cubits (about 23 feet) above its highest peak (Gen. 7:20). That is why one can find ocean life fossils at the tops of mountains. However, God was gracious to Noah and seven of his family; you all know the ark story, so let's just say, eight folks survived and repopulated the world as we know it today. That means every single person alive today is a descendant of Noah! Adam to Noah to you; all one family!
Luke, in the Book of Acts, agreed with this, as he wrote: "God that made the world and all things therein, seeing that He is Lord of heaven and earth, dwelleth not in temples made with hands; neither is worshipped with men's hands, as though He needed any thing, seeing He giveth to all life, and breath, and all things; and hath made of one blood all nations of men for to dwell on all the face of the earth..." (Acts 17:24-26)!
Racism and prejudices are actually sins against one's own family members!
