As Necho, king of Egypt, was on his way to fight against Carchemish, king Josiah of Judah came out against him for battle. Necho assured Josiah that the battle did not involve Judah and that the Lord had commanded him to make haste against the house of Carchemish. In order to turn Josiah’s intervention, Necho reminded Josiah that his intervention would be meddling with the will of God. Josiah refused to listen to the warning and meddled in these matters costing him his life (2 Chronicles 35:22-24). Gamaliel, a doctor of the law, expressed a similar statement when he told his peers that they should let the apostles alone lest they fight against God (Acts 5:34-39).
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.
