I looked it up, and here is the first stanza (Horatius Bonar, 1808-1889):
Not what I am, O Lord, but what Thou art;
That, that alone, can be my soul's true rest;
Thy love, not mine, bids fear and doubt depart,
And stills the tempest of my tossing breast.
Today, shift your attention from trying to make or remake yourself into recognizing what Love is. Love is right here, right now. Rest in Love's being and knowing. Love's presence and activity, not your best human efforts, stills fear both in yourself and others.
