1 Corinthians 15:9–10

9 For I am the least of the apostles,s not worthy to be called an apostle, because I persecutedt the church of God. 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, yet not I, but the grace of God that was with me.u
