'Developed' 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.

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].
