For we all offend in many things. If any man offends not in word, the same is a perfect man, and able also to govern the whole body with restraint.
If I justify myself, my own mouth shall condemn me: if I say, I am perfect, he shall prove me perverse.
For surely there is not a just man upon earth that in doing good does not sin.
Not as though I had already attained it, either were already perfect, but I follow after, if I may lay hold of that for which I have also been laid hold of by the Christ, Jesus.
Be watchful, and strengthen the things which remain, that are ready to die; for I have not found thy works perfect before God.
1 Corinthians 13:10
But when that which is perfect is come, then that which is in part shall be done away.
