Sanctification
Sanctification in the Bible is God's work of setting his people apart and shaping them into holiness. It is not sinless perfection, nor is it passive drift.

Common confusion to avoid

Read these terms together
These neighboring terms keep this definition anchored in the wider biblical picture.
Sanctification is about consecration and transformation
The Bible uses holy language to speak about being set apart to God and being formed into a life that reflects his character.
That gives sanctification both identity and practice.
Sanctification is not self-salvation
Growth in holiness does not replace grace. Scripture presents sanctification as flowing from belonging to Christ, not as a way to earn belonging.
That protects the theme from legalism and despair.
Read sanctification through the Spirit and the word
The New Testament ties holiness to God's truth, God's Spirit, and the daily mortification of sin.
Letters like 1 Thessalonians, Romans, and Ephesians are especially useful here.
