And that ye put on the new man, which after God is created in righteousness and true holiness. Ephesians 4:24. OHC 214.1
No man receives holiness as a birthright, or as a gift from any other human being. Holiness is the gift of God through Christ. Those who receive the Saviour become sons of God. They are His spiritual children, born again, renewed in righteousness and true holiness. Their minds are changed. With clearer vision they behold eternal realities. They are adopted into God's family, and they become conformed to His likeness, changed by His Spirit from glory to glory. From cherishing supreme love for self, they come to cherish supreme love for God and for Christ.... OHC 214.2
Accepting Christ as a personal Saviour, and following His example of self-denial—this is the secret of holiness.58SDA Bible Commentary 6:1117. OHC 214.3
Holiness is not rapture; it is the result of surrendering all to God; it is living by every word that proceedeth out of the mouth of God; it is doing the will of our heavenly Father; it is trusting in God in trial, believing in His promise in the darkness as well as in the light. Religion is to walk by faith, as well as by sight, trusting in God with all confidence, and resting in His love.59The Youth's Instructor, February 17, 1898. OHC 214.4
Sanctification is a state of holiness, without and within, being holy and without reserve the Lord's, not in form, but in truth. Every impurity of thought, every lustful passion, separates the soul from God; for Christ can never put His robe of righteousness upon a sinner, to hide his deformity.... There must be a progressive work of triumph over evil, of sympathy with good, a reflection of the character of Jesus. We must walk in the light, which will increase and grow brighter unto the perfect day. This is real, substantial growth, which will finally attain to the full stature of men and women in Jesus Christ.... OHC 214.5
Conformity to the likeness of Christ's character, overcoming all sin and temptation, walking in the fear of God, setting the Lord continually before us, will bring peace and joy on earth, and ensure us pure happiness in heaven.60Letter 12, 1890. OHC 214.6
