2 Corinthians 13:5-9

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? But I trust that ye shall know that we are not reprobates. 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. For we can do nothing against the truth, but for the truth. For we are glad, when we are weak, and ye are strong: and this also we wish, even your perfection.
