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.
This verse, apart from John 3:16, may be the most recognized and certainly the most quoted verse by those who have little concern for God or the things of God. Matthew 7:1 also happens to be one of the most misinterpreted and misapplied verses in all of scripture. This verse is abused by non-Christians as well as those living a carnal lifestyle. Non-Christians do not want to be held to any biblical standard while carnal Christians attempt to use the verse to avoid having judgment passed upon them and their questionable actions. The spiritual Christian knows that the context of the verse simply discourages judging hypocritically. God never intended for His children to not judge. This passage, along with many others, simply points out the inexcusability of passing judgment upon matters where those judging are likewise guilty of the same actions. The point is not to avoid judgment altogether but to avoid hypocrisy while judging. This truth was taught during the Lord's ministry but also reiterated by the apostle Paul in Romans 2:1.
