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.
Thirty proofs of when sanctification begins (continues): When one is cleansed by the blood of Christ (Heb. 10:29; 1Jn. 1:7-9). When saved to the uttermost and from satan (Heb. 7:25; 1Jn. 3:8-10; 5:18). When redeemed (Luke 1:68-77; 1Cor. 1:30; Heb. 9:12-15; 1Pet. 1:18-23). When one believes truth (2:13). When saved from fornication (4:3-4; Gal. 5:24; 1Cor. 6:9-11). When one becomes the temple of God (1Cor. 3:16-17; 6:19-20; Rom. 8:9). When reconciled to God (2Cor. 5:17-21; Col. 1:20-23; Rom. 5:1-11). When one is saved and purified by faith (Acts 11:14-18; 15:7-11). When brought to obedience to God (1Pet. 1:2; Rom. 6:16-23; 8:12-13). When one is made ready for resurrection to see God (Heb. 12:14; Rev. 20:4-6). When grace brings salvation and the Spirit renews (Tit. 2:11-13; 3:5). When converted and all sins are blotted out (Acts 3:19-21; 26:18). When purged of all sin (Heb. 1:3; 10:1-18; 2Pet. 1:4).
The above points have to do with instantaneous sanctification. There is also progressive sanctification and complete sanctification.
