Prone to Wander

Come, Thou Fount of ev'ry blessing, tune my heart to sing Thy grace;
Streams of mercy, never ceasing, call for songs of loudest praise. ...
O to grace how great a debtor daily I'm constrained to be;
Let that grace now, like a fetter, bind my wand'ring heart to Thee.
Prone to wander - Lord, I feel it - prone to leave the God I love:
Here's my heart, O take and seal it, seal it for Thy courts above.
--Robert Robinson, 1758
