Charles H. Spurgeon on Psalms 38:20

They are mine enemies because I follow the thing that good is. It is a bold attempt to ding Satan out of his nest. If we conform us to the men of this world we find peace with them; they will not discord with us so long as we go their way; but to shame them by a godly life is an affront they cannot digest; and to rebuke their sin, findeth at their hand all that Satan disappointed or corruption provoked can devise. A sleeping dog is quiet, but being stirred, turneth all in barking and biting. Not to do as they do is matter enough of anger, but a reproof is the highest degree of disgrace in their account. All that hatred which they ought to bear to Satan and his instruments, is turned upon God in his rebuking and reclaiming servants. That anger that in remorse should burn against their own sin is set against their reprovers. William Struther.
