When I first read verse 10, it gave me pause because it seems to say works, and not God’s grace is what gives us salvation. It says, Therefore, my brothers, be all the more eager to make your calling and election sure. For if you do these things, you will never fall. But it does not say that. It is simply confirming how our actions should reflect our salvation and relationship with God. It also implies that by our actions we should show the change that comes from a relationship with God.
