Our Sufficiency is of God

1 Do we begin again to commend ourselves? or need we, as some others, epistles of commendation to you, or letters of commendation from you? 2 Ye are our epistle written in our hearts, known and read of all men: 3 Forasmuch 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 in tables of stone, but in fleshy tables of the heart. 4 And such trust have we through Christ to God-ward: 5 Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God; 6 Who 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. 2 Corinthians 3:1-6
