Every person ever born has one thing in common: none of us came into this world in the Garden of Eden. Dr. Bryan Stensaas uses the account of Cain and Abel in Genesis 4 to show why that simple fact makes every human being a sinner in need of a Redeemer. Both brothers knew God, both brought offerings to Him, but only one came God's way. Drawing from Romans 5:12, Leviticus 17:11, and Hebrews 9:22, this study shows why religion, good behavior, and even answered prayer cannot make anyone acceptable to God. Only blood can.
