1 Corinthians 15:9-10

Yes, I am the most insignificant of all the apostles, unworthy even to be called an apostle, because I hunted down believers and persecuted God’s church. But God’s amazing grace has made me who I am! And his grace to me was not fruitless. In fact, I worked harder than all the rest, yet not in my own strength but God’s, for his empowering grace is poured out upon me.
