Refining, Molding, Pruning

But Thou art making me, I thank Thee, sire.
What Thou hast done and doest Thou knows't well.
And I will help Thee; gently in Thy fire
I will lie burning; on Thy potter's wheel
I will whirl patient, though my brain should reel.
Thy grace shall be enough the grief to quell,
And growing strength perfect through weakness dire.
--George MacDonald
