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.
Humility moves God to action. This common theme runs throughout the Bible; however, our passage reveals some truth otherwise hidden. According to Second Chronicles, the people of God are responsible to humble themselves. While doing so, they must also pray, seek God’s face, and turn from their wicked ways. God’s use of the word then in the passage reveals that God’s actions result from the actions of His people. Their humility will move the Lord to action. If, or when, they humble themselves, God hears from heaven, forgives their sin, and heals their land. God takes note when people display humility (Isaiah 57:15; Isaiah 66:1-2). Though some things have changed concerning Israel versus the church, God remains constant and is still looking for humility in the lives of His children.
