I need quotes, so I looked some up. : )
From The Lord, by Romano Guardini:
“It is impossible to consider God as a Christian should, with heart and head full of earthly business, society, worries or pleasures. At first it is a question of choice between good thinking and evil, right doing and wrong; soon, however, we realize that this is not enough; that we must also limit the good and beautiful things to make room for God.”
I like that!
From Transformation in Christ, by von Hildebrand:
"“The more our life is permeated by God, the simpler it becomes. This simplicity is defined by the inward unity which our life assumes because we no longer seek for any but one end: God.”
― Dietrich von Hildebrand, Transformation In Christ
