The words chastening and punishment are like many Bible words that share an overlapping meaning but also exhibit certain variants. A Bible-believer always trusts that God carefully chose His words to accomplish His expressed purpose in any given passage. On the surface, it would seem like the words punish (Leviticus 26:24) and chastise (Leviticus 26:28) seem completely interchangeable, but a thorough study of the whole counsel of God reveals distinctions. One area in which there appears to be a distinction involves the intended purpose of execution. Punishment is the infliction of judgment for the sake of justice, while chastening is the application of judgment for the sake of correction.
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.
