2 Corinthians 13:
5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
6 But I trust that ye shall know that we are not reprobates.
7 Now I pray to God that ye do no evil; not that we should appear approved, but that ye should do that which is honest, though we be as reprobates.
8 For we can do nothing against the truth, but for the truth.
9 For we are glad, when we are weak, and ye are strong: and this also we wish, even your perfection.
10 Therefore I write these things being absent, lest being present I should use sharpness, according to the power which the Lord hath given me to edification, and not to destruction.
