'Perfect' in the Bible

And let endurance have its perfect effect, so that you will be perfect and complete, not deficient in anything.

All generous giving and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or the slightest hint of change.

But the one who peers into the perfect law of liberty and fixes his attention there, and does not become a forgetful listener but one who lives it out -- he will be blessed in what he does.

For we all stumble in many ways. If someone does not stumble in what he says, he is a perfect individual, able to control the entire body as well.
