Theologians have debated the question of whether one can accomplish salvation by faith, or by works of the Law, since the first century. Today, the debate continues, and just like the old days, opinions may differ from one denomination to another.
Personally, I err on the side of the apostle, Paul, who writes the following:
No one can ever be made right with God by doing what the law commands. The law only shows us how sinful we are” (Romans 3:20). “By grace you have been saved through faith, and that, not of yourselves; it is the gift of God (Ephesians 2:8).
All who rely on the works of the law are under a curse, as it is written: ‘Cursed is everyone who does not continue to do everything written in the Book of the Law. Clearly no one who relies on the law is justified before God because ‘the righteous will live by faith’ (Galatians 3:10-11).
Whosoever shall keep the law, and yet stumble in one point, is guilty of all. For he that said Do not commit adultery also said Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law (James 2:10-11).
But, despite Paul’s convincing arguments, and his experience as an expert of the law, many Christians still believe we are justified by works of the Law. Even though, some of those same Christians conveniently pick and chooses which Law they should obey. How, then, can anyone who picks and chooses which law to obey, say he or she is justified by works of the Law. If Jesus were here in the flesh, He would call you out as He did the Pharisees.
“What sorrow awaits you Pharisees? For you are careful to tithe even the tiniest income from your herb gardens, but you ignore justice and the love of God. You should tithe, yes, but do not neglect the most important things. (Luke 11:42).
As i have shown, the laws are mostly rigid. They leave no room for error. If you broke one, you broke all. Therefore, no one can keep them. But God, who knows all things sent His Son to die and free us from the curse of the law.
Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, through whom also we have access by faith into this grace in which we stand, and rejoice in the hope of the glory of God (Romans 5:1-2).
