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 scriptures plainly and repeatedly state that Christ gave Himself as man’s complete and only sacrifice. Yet, the New Testament proclaims that because of salvation, the believer can offer spiritual sacrifices to God (1 Peter 2:5). Before a believer can determine the complete nature of these sacrifices, he must first recognize that any such sacrifices must be made to God only. The Lord declared His jealous nature in the Old Testament when He said, “He that sacrificeth unto any god, save unto the LORD only, he shall be utterly destroyed” (Exodus 22:20). Though much has changed, God still demands that man’s sacrifices be presented to Him and Him alone.
