When darkness long has veil'd my mind,
And smiling day once more appears;
Then, my Redeemer, then I find
The folly of my doubts and fears.

Oh! let me then at length be taught
Why I am still so slow to learn;
That God is love, and changes not,
Nor knows the shadow of a turn.

Sweet truth, and easy to repeat!
But when my faith is sharply try'd;
I find myself a learner yet,
Unskilful, weak, and apt to slide.

But, O my Lord, one look from thee
Subdues the disobedient will;
Drives doubt and discontent away,
And thy rebellious worm is still.
...William Cowper photo
