Through studying the Old Testament Scripture, Paul realized he could not be saved by obeying God’s laws. The prophets knew that God’s plan of salvation did not rest upon keeping the law. Because we have all been infected by sin, we cannot keep God’s laws perfectly. God has provided a way of salvation that depends on faith in Jesus Christ, not on our own efforts. We ignore God’s system and try to earn our salvation whenever we think God accepts us because we do good things or because we are better than other people. In truth, only by faith in Jesus Christ, only by trusting Jesus to take away our sin will we be acceptable to God.
