Genesis 3:15 (ESV)I will put enmity between you and the woman,and between your offspring and her offspring;he shall bruise your head,and you shall bruise his heel.
A loving God frees his prize creation to make their own choices, they rebel against their creator, he immediately starts the process of making a way back for them. Awesome love!
I also like the bit when Adam and Eve are hiding from God and they hear him walking through the garden. Imagine being able to live so closely to God that you recognize the sound of his footsteps--you know when he's approaching. Someday we'll be restored to that level of closeness with God!
