Whence comes this myth that I never made any mistakes or said some things wrong now and then? I think that I am a human being and thus allowed to make some mistakes now and then. I wish I were perfect but to claim so would be stretching the truth just a bit. There are some persons who believe themselves sinless and then there are those who know that Christian justification is by faith, not works, lest anyone should boast. No, we must not boast of being perfect. Our faith is in the forgiveness of sin, not the entire absence of sin. Those who imagine themselves sinless by comparison to some other person are not wise, as the Bible says. We must not imagine that being better than another puts us above reproach. Commending yourself only proves that you really don't understand with Christianity really means. No one is righteous, no, not one, as the Bible says.
2 Corinthians 10:12-18: "For we are not bold to class or compare ourselves with some of those who commend themselves; but when they measure themselves by themselves and compare themselves with themselves, they are without understanding. But we will not boast beyond our measure, but within the measure of the sphere which God apportioned to us as a measure, to reach even as far as you. For we are not overextending ourselves, as if we did not reach to you, for we were the first to come even as far as you in the gospel of Christ; not boasting beyond our measure, that is, in other men's labors, but with the hope that as your faith grows, we will be, within our sphere, enlarged even more by you, so as to preach the gospel even to the regions beyond you, and not to boast in what has been accomplished in the sphere of another. But he who boasts is to boast in the Lord. For it is not he who commends himself that is approved, but he whom the Lord commends."
