“If we could have been saved by being good, then Christ would not have had to die.”
But what if we seek to be made right with God through faith in Christ and then find out that we are still sinners? Has Christ led us into sin? Of course not! Rather, I make myself guilty if I rebuild the old system I already tore down. For when I tried to keep the law, I realized I could never earn God’s approval. So I died to the law so that I might live for God. I have been crucified with Christ. I myself no longer live, but Christ lives in me. So I live my life in this earthly body by trusting in the Son of God, who loved me and gave himself for me. I am not one of those who treats the grace of God as meaningless. For if we could be saved by keeping the law, then there was no need for Christ to die.
Galatians 2:17-21 NLT
Through studying the Old Testament Scriptures, Paul realized that he could not be saved by obeying God’s laws. The prophets knew that God’s plan of salvation did not rest on keeping the law. Because we have all been infected by sin, we cannot keep God’s laws perfectly. Fortunately, God has provided a way of salvation that depends on Jesus Christ, not on our own efforts. Even though we know this truth, we must guard against the temptation of using service, good deeds, charitable giving, or any other effort as a substitute for faith.
