The Lord says, “Listen to me, those of you who try to live right and follow the Lord. Look at the rock from which you were cut; look at the stone quarry from which you were dug.
So this is what has happened: Although the Israelites tried to be right with God, they did not succeed, but the ones God chose did become right with him. The others were made stubborn and refused to listen to God.
So do we have a reason to brag about ourselves? No! And why not? It is the way of faith that stops all bragging, not the way of trying to obey the law.
Does this mean that the law is against God’s promises? Never! That would be true only if the law could make us right with God. But God did not give a law that can bring life.
