It is extremely important for everyone to have a functioning conscience. According to Romans 2:15, the conscience works in man to either accuse or else excuse his thoughts. His thoughts further affect his actions. The more often a conscience is ignored, the sooner it loses its capability to work upon man. The same holds true for any conscience defiled by sin. In John chapter 8, as the Lord dealt with the scribes and Pharisees, the desired inner workings of the conscience can be seen. In this instance, the religious leaders brought a woman before the Lord, accusing her of sin. In response, the Saviour suggested that he that was without sin should be the first to cast a stone in judgment. One by one the consciences of the religious leaders convicted them as they turned and walked away.
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.
