Vida en Cristo - El Verbo, lleno de gracia y de verdad.

The Bible makes it clear that all humans have come from Adam and Eve. Eve is called the mother of all the living (Gen. 3:20).

God's mandate to Adam and Eve was that they would be fruitful and multiply and fill the earth. Obviously this meant their offspring would marry one another.

While Cain and Abel were the first two of Adam and Eve's children, there no doubt were many more. We have no idea how old Cain was when he slew Abel. There may have been many generations of offspring already thriving on the earth at that time.

Cain married a relative as God had intended from the beginning. However, because of sin, the genetic makeup of man was weakened to the point that such intermarriage is no longer permitted. But in the beginning, sin had yet to bring the destruction upon humanity that we now see today.
