Earthly parents sometimes chasten their children according to their own pleasure, but the Lord chastens His children ONLY for their profiting. In addition, earthly parents will sometimes err by disciplining their children for convenience to end the child’s inconvenience brought upon the parent. The end goal turns out to be the satisfaction of the parent rather than the sole good of the child. However, in God’s dealings with His children, He chastens for the benefit of the one receiving the chastening. He uses His chastening to help make His children partakers of His holiness. When they have done wrong, He wants them to repent (Revelation 3:19). When they have gone astray, He wants them to find correction (Job 5:17). God, as a Father, always chooses to do what is best for His children. It is always exclusively for their profit!
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.
As Moses recounted Israel’s time in the wilderness, he reminded God’s people of the reasons for their failure to enter into the land of promise. He rehearsed how it was the people who approached him requesting that spies first be sent into the land to explore it. If the people had trusted God, surveying the land would have been unnecessary. Yet, the people doubted God’s provisions so Moses sent in the spies. When they returned, they expressed stories of giants and walled cities that made the people fear to carry out God’s will. The spies’ report '"discouraged” (Deuteronomy 1:28) the hearts of the people. This loss of courage yielded an unbelief in the people (Deuteronomy 1:32), greatly displeasing the Lord (Hebrews 3:17-19).
