Philemon 1:19

‘ I Paul write it with my own hand, I will repay it, that I say not to you that you owe to me even your own self besides.’

And in order to ensure that Philemon recognised that he really would do it, Paul took the stylus from his amanuensis and wrote down with his own hand, ‘I will repay it’, a total commitment to do what he had promised. Furthermore, in order to make his argument even more forceful, he pointed out that he would not remind Philemon how much he already owed to Paul. For he owed him his own self. This indicates that it was Paul who had brought him to Christ, and to whom he owed his entire spiritual life with all its benefits, and his eternal salvation.
