2:16 to the latter an odor from death to death, but to the former a fragrance from life to life. And who is adequate for these things?

2 Corinthians 3:5-6

3:5 Not that we are adequate in ourselves to consider anything as if it were coming from ourselves, but our adequacy is from God, 3:6 who made us adequate to be servants of a new covenant not based on the letter but on the Spirit, for the letter kills, but the Spirit gives life.
