2 Corinthians 3:1-6

1Do we begin again to commend ourselves? or need we, as some others, epistles of commendation to you, or letters of commendation from you? 2Ye are our epistle written in our hearts, known and read by all men: 3Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not on tables of stone, but on fleshly tables of the heart. 4And such trust we have through Christ toward God: 5Not that we are sufficient by ourselves to think any thing as from ourselves; but our sufficiency is from God;

6Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.1
