It is very important that the saint recognize that he is blameless in Christ at this very moment in time because of Christ’s sacrifice upon the cross. Yet, the Bible warns of one’s condition when the Lord Jesus Christ returns for His own. Thankfully, the scriptures also clearly address this event. According to 1 Corinthians 1:8, the Lord Jesus Christ “shall also confirm you unto the end, that ye may be blameless in the day of our Lord Jesus Christ.” The same truth is expressed in 1 Thessalonians 3:13 when the Bible says that the Lord desires to stablish the believers’ “hearts unblameable in holiness before God . . . at the coming of our Lord Jesus Christ with all his saints.” How is this accomplished? 1 Thessalonians 5:23 offers the answer when it mentions being “preserved blameless.” This preservation is not through man’s efforts but only through the work of Christ. He preserves the Christian positionally blameless.
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.
