2 Corinthians 3:2-5

For your very lives are our “letters of recommendation,” permanently engraved on our hearts, recognized and read by everybody. As a result of our ministry, you are living letters written by Christ, not with ink but by the Spirit of the living God—not carved onto stone tablets but on the tablets of tender hearts. We carry this confidence in our hearts because of our union with Christ before God. Yet we don’t see ourselves as capable enough to do anything in our own strength, for our true competence flows from God’s empowering presence.
