To fingolfin No incest is not okay, that bible says so. To understand the dispensation of a particular period you must study the whole bible, yes the whole bible but then again how can you have understanding when all you do is read other people's work and spend zero time burning your own lamp.
God has a specific dispensation for different biblical periods, this is taught in Bible schools. The command or the Law forbidding to marry one's own sister or brother came during Moses' period or time. In fact most of the laws came during his time. This is the period where God formally and systematically revealed the Religion He wanted Israel to follow. Before this period no official laws to be followed existed.
During Adam and Eve's period the dispensation was simple-
"And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth. "
no laws of forbidding *** between relatives. God commanded them to multiply. Is this offensive? no because at that time they had no idea of what incest is. Their line was still pure. when humanity have reached a population and consciousness where it becomes dangerous to breed within your own relatives, God gave Moses' the law not to have sexual union with your own relatives.
During Adam's time, the genetic pool was pure. It wasn't until later during Moses' time, that incest was then forbidden as the genetic pool became less and less able to stand interbreeding.
