All Orthodox Christians are called to exercise this priestly ministry of prayer which impacts our lives and bears a positive impact on the world. Prayer is synergy with God. He talks to us as we talk to Him. We speak of the four kinds of prayer listed in Scripture: supplications, requests, intercessions and thanksgiving, and what that means for us, and how we produce the fruits of the will of God thereby with a transformative power for ourselves, our households, our communities, and beyond, with a change of orientation toward God.
