2Thessalonians 2:13-14 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God has from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth: Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ.
There is also progressive sanctification and complete sanctification. Proof of progressive sanctification: Statements of Jesus (Luke 9:23; John 8:31; 14:26; 15:3; 16:13-16). Statements of Luke (Acts 13:43; 14:22; 15:41; 16:5; 18:26).

Statements of James (Jas. 1:3-4, 12, 22-27; 2:14-26; 3:2; 4:4-10; 5:1-12). Statements of Peter (1Pet. 1:5-16; 2:1-12; 3:8-12; 4:1-19; 5:1-10; 2Pet. 1:4-10; 3:14-18). Statements of John (1Jn. 1:6-9; 2:1-6, 24-29; 3:1-10; 5:1-18; 2Jn. 1:1, 6, 8; 3Jn. 1:4, 11). Statements of Jude (Jude 1:3, 20-24).
Proof of complete sanctification: Statements of Jesus (Matt. 10:22; 19:27-29; 25:46; Mark 10:29-30; Luke 21:36; John 4:36; 6:27; 12:25; 14:1-3). Statements of Paul (Acts 26:18; Rom. 2:7-10; 5:21; 6:22-23; 8:17-18, 23-25; 13:11; 1Cor. 1:7-8; 15:1-6, 23, 51-58; 2Cor. 4:16-18; 5:9; Gal. 6:7-8; Eph. 1:4, 13-14; 4:13-16; 5:26-27; Php. 1:6; 3:7-14, 20-21; Col. 3:4; 1Thess. 1:10; 2:19; 3:13; 4:13-18; 5:23; Heb. 3:6, 12-14; 6:1-12, 18-19; 10:23, 35-39).

‘To the obtaining of the glory.’ Two things must be done to obtain glory: Stand fast (2Thess. 2:14-15); Hold the true doctrines (2Thess. 2:15; 3:6).
It is folly to talk about “coasting” into heaven without meeting the terms of the gospel. One must not only be called, but he must remain faithful to the call (Rom. 6:16-23; 8:12-13; 1Cor. 9:27; Gal. 5:19-21; 1Thess. 3:8; 1Tim. 5:11-15; 6:19-20; 2Tim. 2:12, 17-18; Jas. 5:19-20; Heb. 3:6, 12-14; 4:1-11; 6:4-9; 10:23-39; 12:14-15; 1Pet. 1:5-13; 2Pet. 1:3-10; 2:20-22).
