“I do not set aside the grace of God; for if righteousness comes through the law, then Christ died in vain.” (Galatians 2:21 NKJV).

God’s grace, as Paul speaks of it here, is that which saves and sustains the one trusting in Christ’s finish work of salvation. Grace is about God’s mercy, while “works righteousness” is about our merit. But grace is more than mercy, for mercy only withholds the punishment we deserve. Yet, grace gives us the opposite of what we deserve. This is not only saving and sustaining grace, it is scandalous grace. For it gives the one who deserves an “F” on life’s test, an “A+.” How is this just? It is just because Christ died in our place. He took our “F” and offers us His “A+.” He took our death and offers us His life. When we attempt to add law-keeping to salvation, we “set aside” grace. And having nullified grace, we nullify the work of Christ on the cross with it. Grace (Greek: χάρις, charis) is God’s unmerited favor freely bestowed on those who having recognized their own inability to save themselves, put their trust in Christ and His finished work of salvation. Grace alone through faith alone in Christ alone saves.
