Somehow a major theme of the Christian life always seems to come back to the fact that knowledge of God and His truth comes through obedience. A challenging theme, to be sure! Our family was reminded of this theme as we continued to follow, in our evening readings, Catherine Marshall's Christy through a crisis of faith while serving as a school teacher in the Appalachian Mountains. Alice Henderson, the Quaker matron of the mission, recommends the following passage from John 17 for Christy's consideration in her moment of crisis.
My doctrine is not mine, but his that sent me. If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself. (Jesus in John 7:17)
