Exhorters are talkers - natural preachers. Give an exhorter a platform and a microphone, and he or she will not fail to have something to say. When they are in the spirit, they are walking, talking encouragement machines, and they are the most fun people to be around. But when they are in the flesh, they would just as soon rip you up one side and down the other. I think they invented the parental lecture complete with finger-shaking, and probably that side-to-side head-bob that some moms do..... When an exhorter is in the flesh, he will tear people down with aplomb. So he must take care that his words are actually building up - that is what the word "exhort" means - to build up. "The wise woman builds her house, but the foolish tears it down with her own hands." (Proverbs 14:1)
