Some time back I posted on the topic of hating sin including an exhortation I preach to myself. This is such an important topic for me- both to learn myself and to pass on to others. Here is a quote I have found helpful from Richard Sibbes commenting on Psalm 97:10:
Ver. 10. Ye that love the LORD, hate evil. It is evident that our conversion is sound when we loathe and hate sin from the heart: a man may know his hatred of evil to be true, first, if it be universal: he that hates sin truly, hates all sin. Secondly, true hatred is fixed; there is no appeasing it but by abolishing the thing hated. Thirdly, hatred is a more rooted affection than anger: anger may be appeased, but hatred remains and sets itself against the whole kind. Fourthly, if our hatred be true, we hate all evil, in ourselves first, and then in others; he that hates a toad, would hate it most in his own bosom. Many, like Judah, are severe in censuring others (Ge 38:24), but partial to themselves. Fifthly, he that hates sin truly, hates the greatest sin in the greatest measure; he hates all evil in a just proportion. Sixthly, our hatred is right if we can endure admonition and reproof for sin, and not be enraged; therefore, those that swell against reproof do not appear to hate sin.
-Richard Sibbes (from Spurgeon’s Treasury of David, on Ps 97:10)
