Adam and Eve’s first sons, Cain and Abel, made a sacrifice to God. Cain, the farmer, made a grain offering and Abel, the rancher, made a lamb sacrifice. Cain’s offering was not acceptable to God and Abel’s was. Why?
Only a lamb sacrifice offered in faith was pleasing to God. Heb. 11:4 tells us, “By faith Abel offered to God a more excellent sacrifice than Cain, through which he obtained witness that he was righteous, God testifying of his gifts; and through it he being dead still speaks.” How does Abel still speak? He points toward a newer and better covenant. In the Old Covenant, animal blood was repeatedly offered for the covering of sins, but in the New Covenant, Jesus shed His blood once for the complete forgiveness of sins.
