More from St. John of the Cross:
Though in this mortal life the soul will never reach to the interior secrets as it will in the next, however much it may hide itself, still, if it will hide itself with Moses, “in the hole of the rock” — which is a real imitation of the perfect life of the Bridegroom, the Son of God — protected by the right hand of God, it will merit the vision of the “back parts”;33 that is, it will reach to such perfection here, as to be united, and transformed by love, in the Son of God, its Bridegroom. So effectually will this be wrought that the soul will feel itself so united to Him, so learned and so instructed in His secrets, that, so far as the knowledge of Him in this life is concerned, it will be no longer necessary for it to say: “Where have You hidden Yourself?”
