Written by Matthew Dickerson, a contemporary author.
Although our outer selves (our visible actions and audible words) reflect the reality of our (invisible) inner lives, our inner selves are not transformed simply by focusing on superficial appearances. Transformation requires getting at the heart, which only God can do. Yet, though the transformational work can only be done by God, and not by our own willpower, we are called both to surrender to that work and to participate in it, which may prove painful as well as joyful. In the imagery of C.S. Lewis, it took the claws of Aslan to remove Eustace’s dragon skin.
Search me, O God, and know my heart! Try me and know my thoughts! And see if there be any wicked way in me, and lead me in the way everlasting! [Psalm 139:23-24]
