Incarnation
Christmas is about incarnation.
In the history of creation, there is not a more significant event than when YHWH is incarnated among his people in the form of a helpless baby in the manger. Love comes near. Presence is the linchpin to redemption. The restoration of humanity comes when God takes his place in the nitty-grittyness of daily life.
God is found not in the temple, or in the mighty cosmos, but in the sweaty stinky filth of a manger. A perfect blend of sacred and secular. It is through the ordinary and the forgotten that salvation finally comes. The path is ignoble and not paved in gold. Those first reached are not the holy, but the mundane.
This is the mode of operation YHWH chooses to use. The incarnation points to the God we serve. It calls us to a way of living and loving in its simple form. Even now God uses a fallen people to be his agents of redemption. The mission of the church is reflected in this: incarnation. God is found in and among his people as they are found among the poor and marginalized. Presence.
Evil in conquered and hope is restored through the weakness of a infant born to teenage peasants in a world of oppression.
Incarnation.
