Christmas is the celebration of the Incarnation: God becoming flesh in Jesus Christ. God is still embodied in the world through the Holy Spirit inhabiting all of us (no, we're not gods, but we present God's continual Incarnation to the world around us).
So in celebration of the Ultimate Incarnation:
How do you continue to experience God's presence and Incarnation around you?
How are you living and showing God's presence to other people around you?
