Anger is not sinful, yet the source of one’s anger sometimes does manifest one’s sinful heart. Perhaps the prophet Jonah best demonstrates this truth. When the Lord first approached Jonah about the need in Nineveh, Jonah clearly displayed his displeasure in seeing the Lord work in the lives of the Ninevites. After experiencing the Lord’s chastening, Jonah appeared to have a heart change. Yet, it did not take long before his anger revealed his true feelings and thoughts. As the hearts of the Ninevites were becoming tender toward the Lord, the prophet’s heart was becoming hardened through anger. His anger revealed that he wanted his own will and not God’s.
Nobody likes to spend time around those who act in a rude or insulting manner. Most people would rather spend people-time with those who focus on saying nice things. However, the truth is that one is just as spiritually dangerous to one's well-being as the other. This is why the Bible warns us to “meddle not with him that flattereth with his lips.” Flattery is directly connected to deceit and covetousness; therefore, God intends for His warning to help Christians avoid people who say nice things deceitfully. These people intend to take advantage of their target. Far too many people have been mistreated and lied to by others whom they thought to be dear friends. It is best to avoid those with flattering lips.
