Zacchaeus—True Friend of God

To God are all the actions of the true friend of Jesus simply and purely directed. He seeks nothing outside of God, but knows that of a truth he has found in him all the good and all the happiness of perfection. Then will he be in some measure transformed in God. He will no longer be able to think, love, understand, remember anything except God and the things of God. He will no longer see himself or creatures except in God; no love will possess him but the love of God, nor will he remember creatures or even his own being, except in God. Such a knowledge of the truth renders the soul humble, makes her a hard judge towards herself, but merciful to others, while earthly wisdom puffs up the soul with pride and vanity.
This is wise and spiritual doctrine, grounded upon the truth, and leading unto the knowledge and service of God, and to familiarity with him. If you want to possess him, you must get rid of earthly affections, not alone for persons, but for every creature, that you devote your mind to the Lord your God with your whole heart and with all your strength, freely, simply, without fear, trusting everything in entire confidence to his all-watchful Providence.
