“God is a jealous lover. He will not share you, so don’t give yourself to anyone but him. He’s unwilling to work in your will unless you’re willing to be entirely his, and his alone. He’s not asking for your help. He’s asking for you. He want you to lock your eyes on him and leave him alone to work in you. Your part is to protect the door and windows, keeping out intruders and flies. And if you’re willing to do that, just ask him, praying humbly, and he will help you immediately.
The Cloud of Unknowing, translated by Carmen Acevedo Butcher
“Satan dreads nothing but prayer. His one concern is to keep the saints from praying. He fears nothing from prayerless studies, prayerless work, prayerless religion. He laughs at our toil, he mocks our wisdom, but he trembles when we pray.”
