Why Does God Guard the Tree of Life?

"These are not curses. This is one curse, only the serpent gets cursed," he says of Adam and Eve's words to each other in Genesis 3. "God doesn't want them to live in this brokenness forever." He asks why god didn't accept abel's offering when kain had brought out first fruits from his flock. But we can look at ourselves and say, 'What am i offering god? What am i giving god?' We just have to give what God gives us - whatever that may be.
