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.
Sin is not necessarily involved in sanctification, because the word means to set apart. God has sanctified both people and material things, and even immaterial things. If sin is not involved in the person or thing set apart, then no sin is cleansed in the process of setting apart:  Material things have been sanctified without taking an old man (satan) out of them: Bread (1Sam. 21:5); the tabernacle and its furniture (Ex. 29:43 – 30:29; Lev. 8:10-15); the priests’ garments (Lev. 8:30); houses and lands (Lev. 27:9-29); meat (1Tim. 4:3-5); Solomon’s temple and furniture (2Chron. 7:16-20; 29:17-19); gates (Neh. 3:1); Mt. Sinai (Ex. 19:23); the offerings (Ex. 29:27); Herod’s temple (Matt. 23:17).  Holy persons have been sanctified who never had an old man in them: God the Father (Lev. 10:3; Num. 20:13; Isa. 5:16; Ezek. 20:41; 28:22-25; 36:23; 38:16; 39:27; 1Pet. 3:15) and Jesus Christ (John 10:36; 17:17-19).  God’s name has been repeatedly sanctified without taking an old man out of it (Isa. 29:23; Ezek. 36:23).  Babies have been sanctified from birth before sinning (Jer. 1:5; Luke 1:15-17; Gal. 1:15) and one never did have an old man in Him (Luke 1:35; John 10:36).  Heathen soldiers and husbands have been sanctified who never were Christians (Isa. 13:3, 17; 1Cor. 7:14).  Believers sanctify God and never take an old man out of Him (1Pet. 3:15).  Christ sanctified Himself though He never had an old man in Him (John 17:19).  The same people were sanctified many times so sanctification cannot be limited to one act (Ex. 19:14, 22; 28:41; 29:33, 44; 30:29; Lev. 8:30).  People have sanctified themselves (Lev. 11:44; 20:7). Did they take an old man out of themselves?  The same people that sanctified themselves (Lev. 11:44; 20:7) were also sanctified by Moses (Ex. 19:10-14) and by God (Ex. 29:43-44; 31:13; Lev. 20:8; 21:8, 15, 23; 22:9, 16). Which ones took the old man out?  All the firstborns of Israel were sanctified at birth (Ex. 13:2; Num. 8:17). If the old man was taken out at this time, then none of them had an old man after that.  Sanctified disciples (John 13:10; 15:3) were further sanctified in the same sense that the sanctified Christ (John 10:36) further sanctified Himself (John 17:17-19).  The seventh day was sanctified without sin and cleaning being involved (Gen. 2:3-4).
However, if sin and filth are involved in a person or a material thing to be set apart unto God, then such must be dealt with to make it presentable to God.
