Ellen G. White describes "santidad" (holiness or sanctification) as a daily, ongoing process of surrendering to God and allowing His Spirit to transform our character. Here are some key points from her writings: 1. True sanctification is complete conformity to the will of God. It involves overcoming rebellious thoughts and feelings, and letting the voice of Jesus bring a new life that fills the whole being. Those who are truly sanctified are humble and do not set up their own opinions as the standard of right and wrong (SL 9.1). 2. Holiness is more than just the absence of unconfessed or unforsaken sin. It is a principle of life that transforms character and controls conduct. Holiness means being wholly dedicated to God—surrendering heart and life to heavenly principles (DA 555.6). 3. God commands us, “Be ye holy; for I am holy,” and the apostle says that without holiness “no man shall see the Lord.” Holiness is agreement with God, and the gospel’s work is to restore God’s image in humanity. We are called to cooperate with God in this work (5T 743.1). 4. Sanctification is a daily work. God does not pardon or bless those who knowingly go against His requirements. Willful sin silences the Spirit and separates the soul from God, regardless of religious feelings (SL 92). 5. Communion with God, love for Him, and practicing holiness bring joy and strength. Through prayer and Bible study, the soul is brought close to God and renewed in true holiness (ApM 24.1). 6. God’s will for us is our sanctification (1 Thessalonians 4:3). If we humble ourselves, confess our sins, and trust in Christ, He will forgive and cleanse us. God asks for complete conformity to His law, and we should desire the fullness of Christ’s grace and righteousness (AA 566.2). 7. The beauty of holiness should fill the hearts of God’s children, and we should seek a deeper understanding of heavenly things (SC 99.3). In summary, sanctification is not self-righteousness, but a humble, continual seeking after God and His righteousness, living in harmony with His will and law. **References:** - White, E. G.
