Love consists not in feeling great things but in having great detachment and in suffering for the Beloved. The soul that is attached to anything, however much good there may be in it, will not arrive at the liberty of Divine union. For whether it be a strong wire rope or a slender and delicate thread that holds the bird, it matters not, if it really holds it fast; for until the cord be broken, the bird cannot fly.
John of the CrossIn tribulation immediately draw near to God with confidence, and you will receive strength, enlightenment, and instruction.
John of the CrossNever 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.
