Here is some wisdom from Richard Sibbes—the kind of wisdom that, if we could just take it to heart, all the way to heart, it would make every difference in our lives.
If we would make it evident that our conversion is sound we must loathe and hate sin from the heart; now a man shall know his hatred of evil to be true, first if it be universal. He that hates sin truly hates all sin. Secondly, where there is true hatred it is fixed; there is no appeasing it, but by abolishing the thing it hates. Thirdly, hatred is a more rooted affection than anger; anger may be appeased, but hatred is 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 but are partial to themselves (Genesis 38:24). 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 with him that tells us of it; therefore those that swell against reproof, hate not sin; only with this caution, it may be done with such indiscretion and self-love that a man may hate the reprover’s proud manner. In disclosing our hatred of sin in others, we must consider our calling; it must be done in a sweet temper, reserving due respect to those to whom reproof is offered, that it may be done out of true zeal, and not out of anger nor pride.
