O Love that will not let me go,
I rest my weary soul in Thee;
I give Thee back the life I owe,
That in Thine ocean depths its flow
May richer, fuller be.
O Light that followest all my way,
I yield my flickering torch to Thee;
My heart restores its borrowed ray,
That, in Thy sunshine blaze, its day
May brighter, fairer be.
O Joy that seekest me through pain,
I cannot close my heart to Thee;
I trace the rainbow through the rain,
And feel the promise is not vain
That morn shall tearless be.
O Cross that liftest up my head,
I dare not ask to fly from Thee;
I lay in dust life's glory dead,
And from the ground there blossoms red
Life that shall endless be.Amen.
