Chastening is not merely a means of judgment implemented by the Lord for wrongdoing, but also serves as a proof of sonship. According to Hebrews 12:6, at some point in every child of God’s life, he will experience the chastening hand of the Lord. Any individual able to freely do wrong without God’s chastening should examine whether or not he is in the faith. The absence of chastening suggests that a person is not a son of God (Hebrews 12:8). Just as any good father will not allow his son to get away with wrongdoing, God the Father does not allow His children to do wrong without suffering the consequences of such actions. Chastisement may be delayed, but it is inevitable.
Chastening is best associated to a parent-child relationship (Deuteronomy 8:5; 2 Samuel 7:14; Proverbs 13:24; Proverbs 19:18; Hebrews 12:6-8). As such, God’s chastening, at least within the New Testament, is only intended for those He calls His sons (1 John 3:2). God chastens His children, not to administer justice, but to strengthen and correct them. The believer does not receive some type of punishment from the Lord resulting from the believer’s sins because these sins have been completely atoned through the shed blood of Christ. However, the saint’s continued practice of sin requires the chastening hand of the Lord in order to conform him into the image of Christ. While chastening is reserved exclusively for sons, a lost man receives only punishment or salvation.
A slothful man hunts and even makes a kill but considers it too much work to prepare and roast that which he killed. He would rather see the meat go to waste than to put forth the effort necessary to preserve the food. However, a diligent man considers his substance to be precious. He has no desire to see something go to waste. Interestingly enough, the Lord Jesus made a point along these lines at the feeding of the five thousand. After He fed the multitude, the Lord Jesus told the disciples to “Gather up the fragments that remain[ed], that nothing be lost” (John 6:12). It was important to the Lord that His followers made full use of the substance given to them of the Father. Nothing was to go to waste. A diligent man considers every part to be precious, even those things the world would allow to spoil.
