John Gill

Having confidence in thy obedience,.... In his obedience of faith to Christ, and his Gospel; he having been made willing in the day of his power to serve him, as well as to be saved by him; and being constrained by his love, and the Spirit of Christ having wrought in him both to will and to do of his good pleasure: l wrote unto thee, knowing that thou wilt also do more than I say; the knowledge the apostle had of Philemon's cheerful obedience to Christ in all the parts of duty, encouraged him to write to him, on this head; believing that he would even do more than he had desired of him.
