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 Bible plainly and repeatedly warns believers not to put their trust in men. In addition to this truth, men are not to trust in themselves. As today's passage shows, sometimes God allows circumstances to come into our lives in order to teach us not to trust in ourselves. If any mere mortal could stake a claim to self-trust, it would have been the apostle Paul. He was “circumcised the eighth day,” “an Hebrew of the Hebrews,” and “a Pharisee” (Philippians 3:5). In spite of this, Paul knew these attributes were not sufficient to trust for eternal life. In fact, he counted these things but dung, that he may win Christ (Philippians 3:8). If Paul understood that he could not put his trust in himself or his accomplishments, everyone else should realize that his or her ability or merits are not worthy of trust.
