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.
Most Christians would consider biblical fasting a very unpleasant undertaking. Considering the complexities of the affliction offered by fasting might better help to understand its value. In our passage, the people of God determined to fast so that they might afflict themselves before the Lord. Several other passages discuss this affliction in even more detail. Isaiah 58:3 and 5 describes the affliction as not merely an affliction of the flesh, but also an affliction of the soul. Additionally, we learn that fasting humbles (Psalm 35:13) and chastens (Psalm 69:10) the soul. Fasting involves much more than merely opposition to one’s flesh. Fasting directly afflicts, chastens, and humbles the soul. Perhaps this is why it is so difficult to fast and so beneficial to do so.
