In the words of Sigrid Undset

And when we give each other Christmas gifts in His name, let us remember that he has given us the sun and the moon and the stars, and the earth with its forests and mountains and oceans - and all that lives and moves upon them.  He has given us all green things and everything that blossoms and bears fruit - and all that we quarrel about and all that we have misused - and to save us from our own foolishness, from all our sins, he came down to earth and gave us himself.
