Proverbs 27:6 Faithful are the wounds of a friend; but the kisses of an enemy are deceitful.
This verse says a lot of how we react to the constructive criticism we talked about earlier. If a friend wounds us it is usually because they are trying to help us. This may hurt for a while but but when it is done in love it should be welcomed. Then on the other hand an enemy flatters you with his lips to try to persuade you to do something that will benefit him. He believes that by flattering you, you will give him whatever he wants. We should pray that God gives us the wisdom and knowledge of who to listen to and who to take instruction from. We should also be able to accept the fact we do not always make the right choices.
