What does it mean to be sanctified by the blood of Christ?

Sanctification is the work of the Spirit that sets believers apart for God's purposes and makes them holy. In Hebrews 13:12, it states that Jesus sanctified the people with His own blood. This means that through His sacrifice, believers are not only justified but also transformed, enabling them to live in a manner that glorifies God. Sanctification reflects both the positional holiness believers have in Christ and the ongoing process of becoming more like Him in our daily lives, resulting in a life committed to God's service.
