Charles Spurgeon Commentary Job 19:11

"He hath also kindled his wrath against me, And he counteth me unto him as [one of] his adversaries." — Job 19:11 (ASV)

Does God ever act like that towards his own children? Yes; there are times when, without any anger in his heart but with designs of love toward them, he treats his children, outwardly, as if he were an enemy to them.

See the gardener going up to that beautiful tree. He takes out a sharp knife, feels its edge to be sure that it is keen, and then he begins pruning it here, gashing it there, and making it bleed in another place, as if he were going to cut it all to pieces.

Yet all that is not because he has any anger against the tree but, on the contrary, because he greatly values it, and wishes it to bring forth more fruit than it has ever done. Do not think that God's sharpest knife means death to his loved ones; it means more life, and richer, fuller life.
