3 Are we beginning to commend ourselves^(A) again? Or do we need, like some people, letters of recommendation^(B) to you or from you? ² You yourselves are our letter, written on our hearts, known and read by everyone.^{(C) 3} You show that you are a letter from Christ, the result of our ministry, written not with ink but with the Spirit of the living God,^(D) not on tablets of stone^(E) but on tablets of human hearts.^(F)

⁴ Such confidence^(G) we have through Christ before God. ⁵ Not that we are competent in ourselves^(H) to claim anything for ourselves, but our competence comes from God.^{(I) 6} He has made us competent as ministers of a new covenant^(J)—not of the letter^(K) but of the Spirit; for the letter kills, but the Spirit gives life.^(L)

²³ Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, ²⁴ since you know that you will receive an inheritance^(A) from the Lord as a reward.^(B) It is the Lord Christ you are serving.
