使徒保相信拯救來自耶穌在十字架上所完成的拯救；但十字架不是一個具有某種法力的法器，而是一個事件，一個完全「順服」上帝旨意的楷模，要做為信徒的模範。 保羅在羅馬書五章19節說：「正如一個人違背命令，眾人成罪人；同樣，一個人順服，眾人成為義人。」他的意思是說：如果人像創世記二至三章所記載的那樣，在領受上帝的恩典和拯救後，不肯順服上帝的誡命，那人就會成為罪人而不能得救；相竑地，人如果願意學習耶穌在十字架上所做的模範，不管面對如何困難的誡命，仍然願意完全「順服」，那人就能再次得到拯救。

The apostle Paul claims that salvation comes form what Jesus has done through the cross. The cross, however, is not a form of magic, rater it is an event through which Jesus shows us that obedience to God’s commandments is the way for people to get salvation. In Romans 5:19, Paul says: “For just as by the one man’s disobedience the many were made sinners, so by the one man’s obedience the many will be made righteous.” What Paul means is that (1) if a man disobeys god’s commandments, as described in Genesis 2-3, he will lose salvation, even though he had received it previously; (2) if a man follows what Jesus has done on the cross and obeys God’s will completely, he will receive salvation again.
