For in many things we all offend. If any man offend not in word, the same is a perfect man, and able also to bridle the whole body.
If I justify myself, my own mouth shall condemn me: if I say, I am blameless, it shall also prove me perverse.
For there is not a just man upon earth, that does good, and sins not.
Not as though I had already attained, either were already perfect: but I follow after, if indeed I may apprehend that for which also I am apprehended of Christ Jesus.
Be watchful, and strengthen the things which remain, that are ready to die: for I have not found your 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.
