God will put up with a great many things in the human heart, but there is one thing that He will not put up with in it--a second place. He who offers God a second place, offers Him no place.
John RuskinWhen men do not love their hearth, nor reverence their thresholds, it is a sign that they have dishonoured both ... Our God is a house-hold God, as well as a heavenly one; He has an altar in every man's dwelling.
John Ruskin
