Wendy, I don't plan on debating what you said at all. Like Jen said, we each get different things from the Bible. That's the beauty of it. It speaks to each individual in their need.

Jen, God being the perfect parent, He knew that Adam and Eve had to suffer the consequences for disobeying Him. He did give them a way out by giving them eternal life when their time on Earth was done. They, too, will stand before the Judgement Throne. Jesus' blood will also redeem them... and like Sky said, the blood sacrifices they made during their lifetime will serve their purpose.

Adam and Eve's sons, Cain and Able, also made sacrifices to God. You'll read about it if you haven't already. Able's sacrifice was accepted because he had pure intentions. Cain's sacrifice wasn't accepted, shown by the fact that the smoke from his fire didn't rise but went down, because he had resentment towards Abel in his heart when he made his sacrifice.
