James 2:24 You see that a person is justified by works and not by faith alone.
24 ὁρᾶτε ὅτι ἐξ ἔργων δικαιοῦται ἄνθρωπος καὶ οὐκ ἐκ πίστεως μόνον.
The title of this post and this verse seem to be at odds with each other, don't they? This is a verse that the Roman Catholic Church uses to defend their view of the gospel. In fact, the Council of Trent declared an anathema on anyone who believes in justification by faith alone. Their view of how one is justified before God is rather complex and I suggest you look it up for yourself to understand just how it is different from that which came out of the Reformation and, if I may say so, that which comes from a plain reading of Scripture.
Yet we have James 2 in our Bibles. Although Luther did take issue with this book, he did consider it to be canonical. What do we do with James 2:14-26, and particularly 2:24? The Greek doesn't help us here. I suppose you could try to do something fancy with the ὅτι and somehow try to suggest some kind of causation with a translation of "because" instead of "that," but I think that the ESV gets it right. What to do?
To me, this passage stands as a defense of what is sometimes called "Lordship Salvation," or as John MacArthur puts it, the gospel according to Jesus. It is clear from reading the Gospels that faith in Christ means action. How can anyone come to know the living God of the universe and not have his life changed? Everything about a person changes when they know the Lord. It has to. Look at what happened to Moses. Look at the apostles after the resurrection. They didn't really "get" what was going on until after Jesus was raised and they received the Holy Spirit. Look at how bold they became afterwards.
I also think that Ephesians 2:10 helps us. That verse tells us that we were made for good works. God didn't save us just to stare at our navels and talk theology, despite what some folks may think. He saved us to action.
To be clear, this does not mean that we suddenly stop sinning. What it means is that our hearts change. We go from being bent toward sin to being bent toward the Lord. There are times (perhaps extensive times) when we go our own ways, but ultimately our hearts are bent toward the Lord. That's what having the Holy Spirit is all about. If we accept the gospel merely as fire insurance we have missed it. The gospel is about God, not about us.
Also, to be clear, we do not do works to earn merit before God, despite what a Roman Catholic might tell you. We work because we are saved. We are not paying off a debt (we cannot), but we are acting out of sheer gratitude. God is glorious and as I've tried to show through this blog, He is worthy of honor and praise. If we aren't inclined to that then we must question the state of our hearts.
To me, it comes down to a simple question. If God is indeed God, how can we encounter Him and not be transformed? Unlike the apostles we have a completed canon. Let's read it and be changed by this awesome transcendent God that we serve.
