Sanctification is a fundamental concept in Christian theology, referring to the process by which believers are set apart for God's purposes and transformed into the likeness of Christ. This transformation involves both a definitive act of God and a progressive work throughout the believer's life. The following scriptures, while not always directly labeled under the term "sanctification," relate to its principles and implications.

General Themes:

· Divine Initiative and Human Response: Sanctification is initiated by God, who sets apart His people and empowers them through the Holy Spirit. Believers are called to respond by living in obedience and holiness.
