COMMENT:
I like where your post was headed, but it needs more information to support your conclusion. Can you help us see how you determined, by progressive revelation, that Cain’s offering lacked faith, and needed blood?
ANSWER:
Earlier I mentioned that faith is believing what God has revealed. What God reveals typically keeps us in right standing with Him. Obedience to what God tells us is what saves us. As we advance through the pages of the Bible God reveals new, or additional things to keep us in relationship with Him. It’s these new, or additional things that I refer to as progressive revelation.
