What does the Bible say about sanctification?

Answered in 84 sources

The Bible teaches that sanctification involves both a definitive aspect where believers are set apart in Christ and a progressive aspect where they grow in holiness over time.

Sanctification in the Bible encompasses the cleansing from sin and the setting apart for God's service, closely aligning with the notion of holiness. This dual concept is understood in two ways. First, there is a one-time definitive sanctification where believers are sanctified fully in Jesus Christ. Secondly, there is a progressive sanctification, which denotes the ongoing growth in holiness that every believer strives for in their spiritual life. This growth is not about quantifiable holiness but rather an increase in the knowledge of Christ and the workings of the Holy Spirit in their lives.
