John Wesley on Job 2:10

Shall we - Shall we poor worms give laws to our supreme Lord, and oblige him never to afflict us? And shall not those great and manifold mercies, which from time to time God hath given us, compensate these short afflictions? Ought we not to bless God for those mercies which we did not deserve; and contentedly bear those corrections which we do deserve. And if we receive so much good for the body, shall we not receive some good for our souls? That is, some affliction, whereby we may be made partakers of his holiness? Let murmuring therefore, as well as boasting, be forever excluded. Sin with his lips - By any reflections upon God, by any impatient or unbecoming expression.
