'Perfect' in the Bible

And let patience have its perfect work, that ye may be perfect and entire, lacking in nothing.

Every good gift and every perfect gift is from above, coming down from the Father of lights, with whom can be no variation, neither shadow that is cast by turning.

But he that looketh into the perfect law, the law of liberty, and'so continueth, being not a hearer that forgetteth but a doer that worketh, this man shall be blessed in his doing.

Thou seest that faith wrought with his works, and by works was faith made perfect;

For in many things we all stumble. If any stumbleth not in word, the same is a perfect man, able to bridle the whole body also.
