Though the means of worldly safety have changed throughout time, people have always put their trust in various things to offer temporary safety. The Bible depicts those who trusted in fenced walls (Deuteronomy 28:52), nations (Isaiah 30:2-3), horses, horsemen and chariots (Isaiah 31:1), weapons (Psalm 44:6), and mountains (Amos 6:1). People today place their trust in weapons, security systems, governments, insurance policies, and even medicines. Though the sources of trust have changed, the Lord remains just as grieved today when men place their trust upon the things of this world rather than upon Him. Ultimately, every source of worldly safety will fail, often in the moment we perceive as our greatest time of need.
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.
