We have two options: either we prove to God our own goodness, or we accept his grace through the faithfulness of Christ. Human goodness is a fiction that many adopt.
I do not treat the grace of God as meaningless. For if keeping the law could make us right with God, then there was no need for Christ to die.
Galatians 2:21 NLT
The fight that Paul takes on in Galatians is this. People wanted to use Moses’ law as a means to establish their own righteousness. They said they could be right with God through the law. They insisted with the Galatian Christians that the way to get to God was through the law, because they had made it into a system of meritorious works.
Paul categorically denies this possibility. Such a fiction negates the necessity for Christ’s death.
Perhaps few today use Moses’ law for self-righteousness, but many use other systems of merit to declare themselves good and to recommend themselves to God. Because of this, the letter to the Galatians continues to be applicable, even more so today, if that’s possible.
For one of the greatest barriers to the gospel is the thought that one’s own goodness excludes the need for Christ’s purifying blood.
