God expects loyalty from man. He is not interested in “worship” that involves Him being one of man’s many gods. In fact, He adamantly opposed this position within the Ten Commandments. There the Lord admonished His people to “have no other gods before” Him (Exodus 20:3). He then warned them not to make nor bow in worship to idols (Exodus 20:4-5). The Lord earned Israel’s loyalty in many ways, but the Bible specifically points to His delivering them from Egypt. It is important to note that God does not expect blind loyalty from man, but He certainly deserves this type of loyalty. He earned man’s loyalty by being his Creator. Yet His ultimate claim to loyalty stems from His offering to redeem fallen man though man is completely unworthy.
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.
