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.
Although the Bible repeatedly warns against fretting, believers fret because of others. Sadly, one’s worry can make the sin of others seem more desirable. We should not fret because of “evildoers” (Psalm 37:1), or “him who prospereth in his way (Psalm 37:7), or “the man who bringeth wicked devices to pass” (Psalm 37:7), or even “evil men” (Proverbs 24:19). Some believers may fret about these people because of their fears, but the scripture offers another reason why believers fret over the wicked. According to Psalm 37:1 and Proverbs 24:19, fretting over the wicked is directly associated to one’s envy toward them. Perhaps believers worry about these people so much because there is a deep-rooted desire to become like them. This desire can be rooted in the fact that those whom we fear are viewed as more powerful, more in control, and even more confident. Eliminate the envy and you will eliminate the fear.
