Ravi Zacharias sums up "Christmas"

"The Christ child in the manger is forever an indication of the great lengths God will go to reconcile his creation, a savior willing to descend that we might be able to ascend with him."
RaviZacharias

And this shall be a sign unto you;

Ye shall find the babe wrapped in swaddling clothes,

lying in a manger.

Luke 2:12
