Pastor Mitchell leads the Mount Zion First Baptist Church in worshipping God by focusing on 4 P's: Praise, Prayer, Proclamation (of the Word) and Power (of the Holy Spirit). He believes that all that we do in worship and service to members and the community comes out of these principles of relationship with God.
