'Fit' in the Bible

to the latter one an aroma from death to death [a fatal, offensive odor], but to the other an aroma from life to life [a vital fragrance, living and fresh]. And who is adequate and sufficiently qualified for these things?

Not that we are sufficiently qualified in ourselves to claim anything as coming from us, but our sufficiency and qualifications come from God.

He has qualified us [making us sufficient] as ministers of a new covenant [of salvation through Christ], not of the letter [of a written code] but of the Spirit; for the letter [of the Law] kills [by revealing sin and demanding obedience], but the Spirit gives life.

Now He who has made us and prepared us for this very purpose is God, who gave us the [Holy] Spirit as a pledge [a guarantee, a down payment on the fulfillment of His promise].
