2 Corinthians 3:4-6

Young's Literal Translation

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.
