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.
We have already learned that our joy is to be found in the Lord and this joy is a special gift from above. With this truth foundational to our study, what are some things that we can do as believers that will bring us lasting joy? Far too many people think joy surfaces once the stresses of life cease or at least begin to diminish. Yet, the Bible teaches that joy can be found only in faithfully serving the Lord. Today's verse reveals that the disciples found joy through what God had done in and through them! Considering a few more scriptural examples of joy should help to solidify our mindset concerning this subject. The Bible records great joy as the people of God willingly sacrificed to the Lord (1 Chronicles 29:17). Proverbs 21:15 reveals that “It is joy to the just to do judgment.” The book of Luke tells us that there is joy in heaven when one sinner repents (Luke 15:7). From these and other examples, we know that true joy will be found when we willingly serve the Lord God, but never in the things of this world.
