As violence escalates, the dependence of the saints upon the Lord for safety becomes increasingly apparent. David serves as a wonderful demonstration of this truth. Seemingly, he constantly found himself threatened by violent men. Shortly after the Lord’s deliverance from the hands of Saul, David wrote a song in which he praised the Lord for saving him from violence (2 Samuel 22:3). Not only was safety from violence the subject of David’s songs, but it was also the theme of his prayers (Psalm 140:1-4). David understood the inevitable presence of violence but also understood that his safety was of the Lord.
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.
