Never give up prayer, and should you find dryness and difficulty, persevere in it for this very reason. God often desires to see what love your soul has, and love is not tried by ease and satisfaction.
John of the CrossHe who interrupts the course of his spiritual exercises and prayer is like a man who allows a bird to escape from his hand; he can hardly catch it again.
John of the CrossThe eternal spring is hidden in this living bread for our life's sake, although it is night. It is here calling out to creatures; and they satisfy their thirst, although in darkness, because it is night. This living spring that I long for, I see in this bread of life, although it is night.
John of the Cross
