Satan transforms himself to appear like the Savior to deceive Eve- ha goal to thwart the plan. Eve transgressed hearkening to Satan and partaking of the fruit. She knows they need to progress and Adam follows Eves wisdom. Once they are cast out they cease not to call on God. They are filled with the Spirit and teach their children. Cain chooses to hearkening to Satan and follow him. He is upset when his offering is not accepted and taught if we seek God and seek His will we will always be accepted. Both teach us to seek god, to repent and call on His name, and to not cease! That is progress.
