Proverbs 29:27
The righteous detest the dishonest; the wicked detest the upright.

If we don't detest the dishonest then we are not righteous. If we are hated because we are righteous, then those who hate us are not righteous.

The righteous hate the wicked, for they cannot stand the vile spirit and actions of the wicked; their hatred is of evil men and their evil actions. But the wicked hate the righteous for their good deeds; their hatred is of good men and good actions.

As the physician hates the disease, but loves the patient, and strives to recover him - he abhors that which is evil, perfectly hates it.

Application

Think about a person who is not doing what is right. Take time to help him/her to come out of his unrighteousness.
