2 Corinthians 3:1-3

Are we starting to brag about ourselves again? Do we need letters of introduction to you or from you, like some other people? You yourselves are our letter, written on our hearts, known and read by everyone. You show that you are a letter from Christ sent through us. This letter is not written with ink but with the Spirit of the living God. It is not written on stone tablets but on human hearts.
