What is the benefit, my fellow believers, if someone claims to have faith but has no [good] works [as evidence]? Can that [kind of] faith save him? [No, a mere claim of faith is not sufficient—genuine faith produces good works.]
Now what use is it, my brothers, for a man to say he “has faith” if his actions do not correspond with it? Could that sort of faith save anyone’s soul? If a fellow man or woman has no clothes to wear and nothing to eat, and one of you say, “Good luck to you I hope you’ll keep warm and find enough to eat”, and yet give them nothing to meet their physical needs, what on earth is the good of that? Yet that is exactly what a bare faith without a corresponding life is like—useless and dead. If we only “have faith” a man could easily challenge us by saying, “you say that you have faith and I have merely good actions. Well, all you can do is to show me a faith without corresponding actions, but I can show you by my actions that I have faith as well.” To the man who thinks that faith by itself is enough I feel inclined to say, “So you believe that there is one God? That’s fine. So do all the devils in hell and shudder in terror!” For, my dear short-sighted man, can’t you see far enough to realise that faith without the right actions is dead and useless? Think of Abraham, our ancestor. Wasn’t it his action which really justified him in God’s sight when his faith led him to offer his son Isaac on the altar? Can’t you see that his faith and his actions were, so to speak, partners—that his faith was implemented by his deed? That is what the scripture means when it says: ‘Abraham believed God, and it was accounted to him for righteousness. And he was called the friend of God.’
Dear friends, do you think you’ll get anywhere in this if you learn all the right words but never do anything? Does merely talking about faith indicate that a person really has it? For instance, you come upon an old friend dressed in rags and half-starved and say, “Good morning, friend! Be clothed in Christ! Be filled with the Holy Spirit!” and walk off without providing so much as a coat or a cup of soup—where does that get you? Isn’t it obvious that God-talk without God-acts is outrageous nonsense?
Brothers and sisters, it doesn’t make any sense to say you have faith and act in a way that denies that faith. Mere talk never gets you very far, and a commitment to Jesus only in words will not save you.
