Erroneous theories of sanctification also spring from neglect or rejection of the divine law. These theories, false in doctrine and dangerous in practical results, are generally finding favor. GrH_c 27.2
Paul declares, “This is the will of God, even your sanctification.” The Bible clearly teaches what sanctification is and how it is to be attained. The Saviour prayed for His disciples: “Sanctify them through thy truth: thy word is truth.” And Paul teaches that believers are to be “sanctified by the Holy Ghost.” 1 Thessalonians 4:3; John 17:17; Romans 15:16. GrH_c 27.3
What is the work of the Holy Spirit? Jesus told His disciples: “When he, the Spirit of truth, is come, he will guide you into all truth.” John 16:13. And the psalmist says: “Thy law is the truth.” Since the law of God is “holy and just and good,” a character formed by obedience to that law will be holy. Christ is a perfect example of such a character. He says: “I have kept my Father's commandments.” “I do always those things that please him.” John 15:10; 8:29. The followers of Christ are to become like Him—by the grace of God to form characters in harmony with the principles of His holy law. This is Bible sanctification. GrH_c 27.4
