1. Messiah's Office as Priest 2. Our Office as Priest The sermon centers on the truth that Christ, as the eternal High Priest, fulfills the Old Testament priestly office by sanctifying humanity through His sacrifice, enabling believers to enter God's presence. Drawing from Exodus 19 and Hebrews 13, it emphasizes that the priest's essential work is not merely sacrifice, but the preparation of God's people for holy fellowship by sanctifying them, interceding for them, and bringing them into God's presence. In the New Testament, this reality is fulfilled in Christ, who is both the perfect sacrifice and the eternal intercessor, and believers are now called a 'royal priesthood' (1 Peter 2:9), called to sanctify themselves, draw near to God in worship and prayer, offer spiritual sacrifices of praise and thanksgiving, and intercede for others. The sermon calls the congregation to live out this priestly identity with humility and intentionality, rejecting the notion that personal holiness is earned, while embracing the grace of Christ's imputed righteousness as the foundation for a life of continual devotion, sacrifice, and love toward others.
