1 Corinthians 15:10 says: by the grace of God I am what I am, and his grace to me was not without effect. No, I worked harder than all of them — yet not I, but the grace of God that was with me. Paul was one of the most disciplined builders in history. He also knew that everything he built rested on grace, not on his own consistency. The long game is not won by people who never fall short. It is won by people who, every time they fall short, understand that grace makes it possible to start again tomorrow.
