Brother Lawrence
“It is, however, necessary to put our whole trust in God, laying aside all other cares, and even some particular forms of devotion, though very good in themselves, yet such as one often engages in unreasonably, because these devotions are only means to attain the end. So when by this exercise of the presence of God we are with Him who is our end, it is then useless to return to the means; but we may continue with Him our commerce of love, persevering in His holy presence, one while by an act of praise, of adoration or of desire; one while by an act of resignation or thanksgiving; and in all the ways which our spirit can invent.”
