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.
Unfortunately, far too many people today seek to hide the truth behind their lies. This condition is nothing new. In fact, the rulers of Jerusalem claimed to “have made lies our refuge, and under falsehood have we hid ourselves” (Isaiah 28:15). The Lord quickly answered their false assumption. He informed them that their lies would not stand when the Lord passed through their midst with judgment (Isaiah 28:16-19). In verse 20, God offered an illustration of the manner in which their lies would fail to protect them. He said, “the bed is shorter than that a man can stretch himself on it: and the covering narrower than that he can wrap himself in it” (Isaiah 28:20). In other words, no matter how big, well thought out, or cunning a man’s lies may be, they will never be enough. Hiding behind lies is useless and fruitless. Lies can neither support a man nor hide him when the trouble arrives.
