Believers are not to speak, look, think, or act like the world. In every way possible, believers are to remain separate and distinct. Believers saved for any length of time have noticed the drastic shift in what the world defines as acceptable and unacceptable behaviour. For instance, man in general once disdained the idea of tattoos, body piercings, and cuttings in the flesh (Leviticus 19:28). Yet, now these things are not only acceptable but even practiced by believers. The world used to distinguish between men and women, even taking note of one’s hair length (1 Corinthians 11:14-15). Yet these distinctions have been blurred and in some cases eliminated with men attempting to become women and women men. The people of God are not to follow along with cultural shifts, but abide rather in the unchangeable words of God.
In the most basic sense, punishment is directed toward those who have done wrong. Though any particular punishment may seem harsh by those receiving the punishment, God intended it to be a calculated response toward wrongdoing. Though there are some passages in the Old Testament that indicate punishment was directed toward the people of God (Ezra 9:13; Hosea 12:2), the vast majority of references demonstrate that it was intended for the enemies of God (Psalm 149:7; Proverbs 11:21; Isaiah 10:12; Isaiah 13:11; Isaiah 24:21; Isaiah 26:21; Isaiah 27:1; Jeremiah 25:12; Jeremiah 46:25). A careful study of the New Testament will strengthen the distinction as there are no references to God punishing His people.
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.
