God Who is about to be born has no house nor cradle ready for Him, so do you prepare your heart for His dwelling-place. Let it be warm with love, for the Babe is chilled; but still, if it be only tepid, the shivering Infant will bring it greater heat. The more He suffers from the cold for us, the more strongly does He prove His love, and so deserves our love still more.
--St. John of Avila, Letters, XXI
