 Again, the Apostle Paul writing, but now he's writing not about himself, his own testimony, he's writing to the church of Corinth, and he says this, 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. You know, he says, look, you've got to know yourself.
