2 Corinthians 3:5-6 AMP
5 Not that we are fit (qualified and sufficient in ability) of ourselves to form personal judgments or to claim or count anything as coming from us, but our power and ability and sufficiency are from God.
6 [It is He] Who has qualified us [making us to be fit and worthy and sufficient] as ministers and dispensers of a new covenant [of salvation through Christ], not [ministers] of the letter (of legally written code) but of the Spirit; for the code [of the Law] kills, but the [Holy] Spirit makes alive. [Jer. 31:31.]
