Proverbs 9:8-9 Reprove not a scorner, lest he hate thee: rebuke a wise man, and he will love thee. Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning.
Do you mock or do you learn? Are you wise or are you a jerk? The teacher, preacher, discipler gets a lesson here. If they are a scorner, bad attitude, mocker then they will only hate you when you try to teach them something.
If you teach a wise man he will want to learn. He will take it to heart and apply it to his life.
Which are you? Will you listen or do you already know everything?
