And after the flood we are told that the curse [black skin] that had been pronounced upon Cain was continued through Ham’s wife, as he had married a wife of that seed. And why did it pass through the flood? Because it was necessary that the devil should have a representative upon the earth as well as God. . . .
Why is it, in fact, that we should have a devil? Why did the Lord not kill him long ago? Because he could not do without him. He needed the devil and a great many of those who do his bidding to keep men straight, that we may learn to place our dependence upon God, and trust in him, and to observe his laws and keep his commandments. When he destroyed the inhabitants of the antediluvian world, he suffered a descendant of Cain to come through the flood in order that he might be properly represented upon the earth.
LDS President John Taylor, Journal of Discourses, 22:304, 23:336
Where oh where to begin!
Firstly, we are not told in Genesis 4:15 exactly what was the mark that God gave Cain, but it certainly wouldn’t have been black skin color or it would have said God gave him more than a “mark.”
Secondly, the mark wasn’t a curse — it was a mark of protection!! Thirdly, there is no evidence from Scripture that Ham’s wife was a descendant of Cain—that is just a made up idea by the Mormons.
Thirdly, nowhere in Scripture does it say that Cain was representing the devil, or that his offspring were representatives of the devil. This, again, is an idea totally made up by the Mormons.
Fourthly, the idea the God can’t do without the devil certainly puts limits on God and His sovereignty! The Mormon god proves to be incompetent.
Fifthly, how is it that the devil can do God’s bidding “to keep men straight”? Isn’t that the work of the Holy Spirit in believers?
Lastly, explain why the devil needed “to be properly represented upon the earth”?
All this unbiblical nonsense comes about in order to shore up the false teachings of Joseph Smith. These teachings include the lie that Satan is a brother of Christ rather than a being created by Christ (as the Bible teaches), that spirits in the pre-existence were all brothers and sisters (the Bible teaches NO pre-existent spirits); that these spirits chose to follow Christ or Satan and those who remained neutral received the curse of dark skin when they come to earth (pure racist ideology), and that Cain was apparently the first earthbound soul to have this curse (which begs another question about when this so-called rebellion took place); and that those who followed Satan became demons (whereas the Bible teaches that the demons are fallen angels, which are a different created being than are humans).
Mormons, you’ve been fed a lot of science-fiction fairy tales which totally contradict the truth of the Bible. Learn the truth and leave Mormonism.
