'Perfecting' in the Bible

We are glad when we are weak [since God’s power comes freely through us], but you [by comparison] are strong. We also pray for this, that you be made complete [fully restored, growing and maturing in godly character and spirit—pleasing your heavenly Father by the life you live].

[and He did this] to fully equip and perfect the saints (God’s people) for works of service, to build up the body of Christ [the church];

I am convinced and confident of this very thing, that He who has begun a good work in you will [continue to] perfect and complete it until the day of Christ Jesus [the time of His return].

for this [first or outer tabernacle] is a symbol [that is, an archetype or paradigm] for the present time. Accordingly both gifts and sacrifices are offered which are incapable of perfecting the conscience and renewing the [inner self of the] worshiper.
