The character of God is revealed through His self-sacrificial, covenantal love and mercy. And His justice and righteousness are satisfied and fulfilled through His self-sacrifice. A lamb was slain to cover the nakedness of Adam and Eve following the Fall. That first sacrifice, and every animal sacrifice that followed, pointed toward a future sacrifice - a once-for-all-time, perfect sacrifice - Jesus, the Lamb of God who takes away the sins of the world. God’s sacrifice is still sufficient.
