See then, dear friend, that the weakness of your faith will not destroy you. A trembling hand may receive a golden gift. The Lord’s salvation can come to us though we have only faith as a grain of mustard seed. The power lies in the grace of God, and not in our faith. Great messages can be sent along slender wires, and the peace-giving witness of the Holy Spirit can reach the hearts by means of a thread-like faith which seems almost unable to sustain its own weight. Think more of him to whom you look than of the look itself. You must look away even from your own looking, and see nothing but Jesus, and the grace of God revealed in Him.
