1Thessalonians 4:1-7 Furthermore then we beseech you, brethren, and exhort you by the Lord Jesus, that as you have received of us how you ought to walk and to please God, so you would abound more and more. For you know what commandments we gave you by the Lord Jesus. For this is the will of God, even your sanctification, that you should abstain from fornication: That every one of you should know how to possess his vessel in sanctification and honour; Not in the lust of concupiscence, even as the Gentiles which know not God: That no man go beyond and defraud his brother in any matter: because that the Lord is the avenger of all such, as we also have forewarned you and testified. For God had not called us unto uncleanness, but unto holiness.
There are fourteen requirements of the will of God in sanctification (4:3-18) – (continues): Do not despise men (4:8). Love one another (4:9; 1Cor. 13:1-13). Increase in love (4:10; 3:12). Study to be quiet (4:11; 2Tim. 2:15). Be diligent in business (4:11). Work with your hands (4:11; 1Cor. 4:12; Eph. 4:28; 2Thess. 3:10). Walk honestly before men (4:12). Have a bright hope (4:13-17). Comfort one another (4:18). ‘Sanctification’ [Greek: hagiasmos] consecration. Translated “holiness” (4:7; Rom. 6:19, 22; 1Tim. 2:15; Heb. 12:14) and “sanctification” (4:3-4; 1Cor. 1:30; 2Thess. 2:13; 1Pet. 1:2).
The doctrine of sanctification – a separation unto God FROM a profane, secular, and carnal use TO a sacred, religious, and spiritual use. The words “sanctify” and “sanctified” are used 132 times; “sanctification” 5 times (New Testament only); and “sanctifieth” 4 times (New Testament only) – 141 times total in Scripture: 110 times in the Old Testament and only 31 times in the New Testament A study of the various passages shows that to sanctify means to set apart from other uses to God’s particular use, not to cleanse from sin or rid of carnal nature (sometimes called “the old man” or Adamic nature). Even Christ, the Sinless One, was sanctified (John 10:36; 17:19). Where humans are concerned one begins to be sanctified when he begins to consecrate his life to God, and the process is continued as he continues in his dedication (1Cor. 1:30; 6:11; 2Thess. 2:13; 1Jn. 1:7-9; 3:8-10; 5:1-4, 18).
