1 Cor. 15:10 – But by the grace of God I am what I am, and his grace toward me was not in vain. On the contrary, I worked harder than any of them, though it was not I, but the grace of God that is with me.
Paul was the prototype in the New Testament of a person effected by the grace of God. To understand Paul you have to have an understanding of grace. What is grace? The most common answer you will get when you pose that question is this, “unmerited favor”. That is not really an accurate answer. “Unmerited favor” seems to imply that grace is getting good things from the Lord that our behavior doesn’t warrant. That is not grace. Bible grace is so much more than that. Grace is the influence of God on our souls that makes spiritual things attractive to us. In other words, grace transcends the things and blessings of this world and brings us into a place where “only God” will do for us. We begin to follow the Lord with all of our might because we delight in Him and in doing His work. Here is how Albert Barnes describes this verse.
“But by the grace of God I am what I am – By the “favor” or mercy of God. What I have is to be traced to him, and not to any native tendency to goodness, or any native inclination to his service, or to any merit of my own. All my hopes of heaven; all my zeal; all my success; all my piety; all my apostolic endowments, are to be traced to him. Nothing is more common in the writings of Paul, than a disposition to trace all that he had to the mere mercy and grace of God. And nothing is a more certain indication of true piety than such a disposition… He had been enabled by the grace of God, to labor more than all the rest, and he had thus shown that he had not been insensible of his obligations.”
So not only does grace cleanse me of my sin, it also frees me from the power of sin. It works in the most unexpected way, it works through our enjoyment or pleasures. We used to love sin and now we love Him and His kingdom. That’s what happened to Paul at his conversion. Grace arrested him, grace forgave him, and grace consumed him with a new passion. From the day of his conversion onward, Paul was consumed and transformed by grace. That’s why he said, “by the grace of God I am what I am”.
