2 Corinthians 3:4-6

YLT(i) 4 and such trust we have through the Christ toward God, 5 not that we are sufficient of ourselves to think anything, as of ourselves, but our sufficiency is of God,
6 who also made us sufficient to be ministrants of a new covenant, not of letter, but of spirit; for the letter doth kill, and the spirit doth make alive.
