'Qualified' in the Bible

The Spirit of the Lord God is upon me,Because the Lord has anointed and commissioned meTo bring good news to the humble and afflicted;He has sent me to bind up [the wounds of] the brokenhearted,To proclaim release [from confinement and condemnation] to the [physical and spiritual] captivesAnd freedom to prisoners,

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.

giving thanks to the Father, who has qualified us to share in the inheritance of the saints (God’s people) in the Light.

Now an overseer must be blameless and beyond reproach, the husband of one wife, self-controlled, sensible, respectable, hospitable, able to teach,

The things [the doctrine, the precepts, the admonitions, the sum of my ministry] which you have heard me teach in the presence of many witnesses, entrust [as a treasure] to reliable and faithful men who will also be capable and qualified to teach others.
