"The sins of others work for good, as they work in us the stronger opposition against sin. " The wicked have made void thy law; therefore I love thy commandments " (Psalm cxix. 126, 127). David had never loved God's law so much, if the wicked had not set themselves so much against it. The more violent others are against the truth, the more valiant the saints are for it. Living fish swim against the stream; the more the tide of sin comes in, the more the godly swim against it. The impieties of the times provoke holy passions in the saints; that anger is without sin, which is against sin. The sins of others are as a whetstone to set the sharper edge upon us; they whet our zeal and indignation against sin the more." (Thomas Watson)(A Divine Cordial)
