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.
Man has no greater high priest than the Lord Jesus Christ for the Lord knows what man endures. Like man, He was tempted in all points. In a basic sense, man’s temptations involve three distinct facets: “the lust of the flesh, and the lust of the eyes, and the pride of life” (1 John 2:16). During the Lord’s earthly ministry, He faced and conquered temptation in each area (Matthew 4:1-11). As such, the Lord is “touched with the feeling of our infirmities” (Hebrews 4:15). He knows what it is like to face the temptation to depart from the will of God. He knows what it is like to be tempted to sin against the Heavenly Father. Yet, He differs from man in that His temptation was without the knowledge of sin, for He was victorious in all points.
