2 Corinthians 3:5-6

What have I to recommend me but you, — you who are my work? But even this allows me no power of counting anything to myself, it is simply the fact that God has made me the minister of His new covenant. My only sufficiency is the irresistible power of this fact. Now the old covenant defined and elaborated the doom of sin, and showed the inevitableness of death as its penalty. That was its truth, and hence its glory. And we read that the man appointed to serve this absolute covenant of sin’s reward was yet invested with divine glory. That doom was engraven, we read, in letters on stone tables, and it slew.
