The psalmist proclaims: “Behold, how good and how pleasant it is for brethren to dwell together in unity!” Unlike the unity of unbelievers and the heathen, the Lord rejoices in the righteous unity of His people. King David was someone who knew and experienced the difficulties of division. He spent a great deal of his life running from a king and those who were against him. Even in the beginning of his reign, the people were divided (2 Samuel 2:8-11). It was not until 7 1/2 years later that the people were united in David (2 Samuel 5:1-5). When the people dwelt in unity, David rejoiced. He likened it to the source of spiritual life for the nation of Israel, the priesthood (Psalm 133:2), and to the source of physical life in the dew of Hermon (Psalm 133:3). In other words, the right kind of unity gave life and hope to the nation!
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.
