2 Corinthians 3:2-5

Mace(i) 2 you are my epistle, your conversion being writ in. my heart, known and read by all men: 3 which shows you to be the epistle of Christ, written by my ministration, not with ink, but with the spirit of the living God; not on tables of stone, but on living tables of the heart. 4 It is by Christ that I have this confidence in God. 5 not that I am sufficient of myself to effect any thing by the strength of my own reason: but my sufficiency is from God.
