There is a world of difference between a slave and a son. Through our faith in Christ, we become sons of God and heirs of the promise of blessing that God made to Abraham. We should not attempt to go back under the slavery of the law or a system of performance. Grace and law do not mix. Those who have been saved through faith in God’s grace should not try to mix in the law or works. They must make a clean break and rely on the grace of God.
