And they sang a new song, saying:"You are worthy to take the scroll, and to open its seals; for You were slain, and have redeemed us to God by Your blood out of every tribe and tongue and people and nation, and have made us kings and priests to our God; and we shall reign on the earth" (Rev 5:9-10).
Every marketplace believer has a calling to be both king and priest. Like Melchizedek who was also a king and priest, we too are called to both assignments. Moses' operated as both a king and priest. He operated as a king as the leader of an entire nation. His role as a king was a very public one with the people. But he also operated as priest, going before the people on their behalf spiritually by interceding on their behalf.
This does not mean we are called to vocational "priestly" pastorate ministry; it means we are called to intercede for those we are called to serve. We are called to lay down our lives for that worker next to us in the cubicle, that CEO who operates at the top of your cultural mountain, or that government leader who wants to change your values in your state or nation. We are called to rebuild the ancient ruins.
