'Fully' in the Bible

And let endurance have its perfect result and do a thorough work, so that you may be perfect and completely developed [in your faith], lacking in nothing.

Then after desire has conceived, it gives birth to sin, and when sin is fully grown, it gives birth to death.

ye did not judge fully in yourselves, and did become ill-reasoning judges.

For we all stumble and sin in many ways. If anyone does not stumble in what he says [never saying the wrong thing], he is a perfect man [fully developed in character, without serious flaws], able to bridle his whole body and rein in his entire nature [taming his human faults and weaknesses].

But He gives us more and more grace [through the power of the Holy Spirit to defy sin and live an obedient life that reflects both our faith and our gratitude for our salvation]. Therefore, it says, “God is opposed to the proud and haughty, but [continually] gives [the gift of] grace to the humble [who turn away from self-righteousness].”
