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.
The book of Proverbs frequently incorporates the tools of comparison and contrast for the purpose of teaching specific truths. In today’s passage, a liberal soul is likened to one who waters. The passage also mentions that being made fat is likened to being watered. In other words, a liberal reaps the benefits of his own liberality. Proverbs chapter 3 also sets forth the principle of sowing and reaping as man is told to “Honour the LORD with thy substance, and with the firstfruits of all thine increase: So shall thy barns be filled with plenty, and thy presses shall burst out with new wine” (Proverbs 3:9-10). When a man with a sincere heart liberally cares for the Lord and His people, the Lord will return his liberality back to him.
