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.
The Bible repeatedly referred to Christ's meekness during His interaction with others. Meekness implies a gentle response toward those who attack. Jesus Christ demonstrated meekness to its perfection on the cross of Calvary when He said, "Father, forgive them; for they know not what they do" (Luke 23:34). Peter emphasized this point when he said of Christ, “Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously” (1 Peter 2:23). Isaiah prophesied of Christ, “He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth” (Isaiah 53:7). The Bible says that Jesus was mocked, spit on, and struck by His accusers, yet He displayed incomprehensible meekness.
