If animals of different species mate, their offspring would become infertile because the spirit would be confused as to whether they should be like the mother, or like the father. If the offspring is like the mother, then their offspring would all be like the mother. However, the father’s spirit is part of the equation. It is for this reason that God seeks to keep the species separate reproductively.
it is for this same reason that individuals who have the light of God in them should not be joined in matrimony with individuals who worship Satan. If they have the Mark of the Beast, you should assume that they worship Satan. The Lord God Almighty cannot guarantee that your children will be in the millennial kingdom if your spouse is a demon, or is inhabited by demons from hell.
