The biblical concept of sanctification includes the idea of perfection, first given forensically to an individual by God’s grace and then progressively brought about into the individual’s experience by the Holy Spirit. It explains the differences between justification and sanctification, highlighting that justification is the gift of perfect righteousness given by Christ's sacrifice, while sanctification is involved in this but also in the ongoing process of becoming more Christ-like. The message encourages believers to rely on the Holy Spirit for spiritual growth and to understand that their ultimate perfection will be realized in glory.
