Today's passage proves the Bible truth that our thoughts are not God’s thoughts, neither our ways His ways (Isaiah 55:8-9). God's thoughts are always unimaginably loftier than ours. Unlike God, our thoughts are bound by our limited knowledge. Contrary to the Lord’s, our knowledge is easily corrupted through various influences. This is why scripture reading and preaching often conflicts with our natural thought process. For instance, our natural mind considers rebuke something harmful, negatively affecting the person receiving it. We also naturally consider flattery as something beneficial and uplifting to the recipient. Yet, we have already seen how flattery can be harmful, but have you ever considered the superiority of a rebuke? The Bible says rebuke is better because of what it yields “afterwards.” In the long run, rebuke is far superior to flattery.
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.
Fasting, similar to other actions in life, has specific purposes and appointed times. The Bible offers various reasons why people might fast: an immediate need in prayer (2 Samuel 12:16), a need to loosen the bands of wickedness or undo heavy burdens (Isaiah 58:6), during times of elevated conflict or duty in service (Matthew 17:21; Acts 13:3), as a symbol of mourning (2 Samuel 1:12), and as an outward manifestation of true repentance (Jonah 3:5). This list is not exhaustive, but simply demonstrates that God’s people have many good reasons for fasting. Even if none of these circumstances surfaces in our lives, we should fast because we know that the Lord expects us to do so.
