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 likens a mature Christian to one who exercises. Exercise involves work for it to be most profitable. Many people start exercising with exuberance and zeal, yet quit when the workout begins to get difficult. This too unfortunately applies to those who start out wanting to live a godly life. Too many Christians quit simply because spiritual growth takes a lot of hard work and effort. Today’s passage contrasts the difference between a babe in Christ and a believer enjoying the meat of God’s word. The babe enjoys the milk of God’s word (the basic truths) but the milk limits the extent of his growth; whereas, the mature Christian wants to grow stronger through learning the truths that babes cannot yet handle. The strong Christian exercises his senses enabling him to discern between good and evil. He works hard. He does not quit though times get tough. He keeps reading his Bible. He keeps praying. He keeps obeying the Lord. When he stumbles, he simply picks himself back up, brushes himself off, and keeps moving forward, onward, and upward. So get up and go!
