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.

Although I am innocent, my mouth would condemn me; although I am blameless, it would declare me perverse.

For there is not one truly righteous person on the earth who continually does good and never sins.

Not that I have already attained this -- that is, I have not already been perfected -- but I strive to lay hold of that for which Christ Jesus also laid hold of me.

Wake up then, and strengthen what remains that was about to die, because I have not found your deeds complete in the sight of my God.

but when what is perfect comes, the partial will be set aside.
