Sanctify them through thy truth: thy word is truth. John 17:17. OHC 212.1
What is sanctification? It is to give one's self wholly and without reserve—soul, body, and spirit—to God; to deal justly; to love mercy, and to walk humbly with God; to know and to do the will of God without regard to self or self-interest; to be heavenly-minded, pure, unselfish, holy, and without spot or stain.55Manuscript 65, 1886. OHC 212.2
It is through the truth, by the power of the Holy Spirit, that we are to be sanctified—transformed into the likeness of Christ. And in order for this change to be wrought in us, there must be an unconditional, wholehearted acceptance of the truth, an unreserved surrender of the soul to its transforming power. OHC 212.3
Our characters are by nature warped and perverted. Through the lack of proper development they are wanting in symmetry. With some excellent qualities are united objectionable traits, and through long indulgence wrong tendencies become second nature, and many persons cling tenaciously to their peculiarities. Even after they profess to accept the truth, to yield themselves to Christ, the same old habits are indulged, the same self-esteem is manifested, the same false notions entertained. Although such ones claim to be converted, it is evident that they have not yielded themselves to the transforming power of the truth.... OHC 212.4
If the one who is thus misrepresenting Christ could know what harm has been wrought by the faults of character which he has excused and cherished, he would be filled with horror.... OHC 212.5
Let none feel that their way needs no changing.... None can walk safely unless they are distrustful of self, and are constantly looking to the Word of God, studying it with willing heart to see their own errors, and to learn the will of Christ, and praying that it may be done in and by and through them. They show that their confidence is not in themselves, but in Christ. They hold the truth as a sacred treasure, able to sanctify and refine, and they are constantly seeking to bring their words and ways into harmony with its principles.56The Review and Herald, April 12, 1892.
