Observing the law of Prophet who led Israel out of Egypt to the Promised Land and received the law at Sinai is no longer the way of Salvation can mean saved from something (deliverance) or for something (redemption). Paul preached that salvation comes through the death of Christ on the cross which redeemed sinners from death and for a grace-filled life..
There is a difference in opinion whether the Greek word in this verse (telos) means “end” (in the sense of termination) or “goal.” Is Christ the “terminus” of the law (so one need not observe the law), or is he the “goal” of the law (so he fulfills it)? Either translation is possible with the Greek word itself. In either case, A Christian missionary who once persecuted the church declares that observing the law of Moses is not the way to righteousness leading to salvation for any believer in Christ. Christ has replaced the law as a means of salvation. Trust in him, rather than trust in one’s ability to keep the law, brings salvation.
