Why is Christ's role in sanctification important for Christians?

In the believer's journey, Christ’s role in sanctification is vital because He is the source of all spiritual growth and holiness. 1 Corinthians 1:30 teaches that Christ has become for us wisdom, righteousness, sanctification, and redemption, indicating that without Him, we cannot achieve true holiness. He not only cleanses us from our sins but also empowers us to live in obedience through His Spirit. By looking to Christ, believers are transformed into His likeness, showcasing the importance of His involvement in the sanctifying process.
