Question: What is the definition of sanctification? 1. To be separated or set apart unto God. Often will be translated by the equivalent term "holiness." 2. Comes as a result of obedience to truth (Jno.17:17; 1 Cor. 6:11) a. Possible only in Christ 1 Cor. 1:30. b. God's will 1 Thes. 4:3; that to which He calls us v.7. c. Essential Heb. 12:14. 3. Involves two important aspects: a. Separation from that which is sinful (1 Thess. 4:3; 2 Cor. 7:1; Titus 2:11,12). b. Separation unto God, and the doing of His will (1 Pet. 2:11). Jesus is our example in this. 4. What it does not mean is sinless perfection (Rom.3:23; 1 Jno. 1:7-9). 5. Other passages: Opposite is uncleanness (1 Thes. 4:7) Rom. 6:19,22; 1 Tim. 2:15.
