The Urantia Book opens:
1:0.1 (21.1) THE Universal Father is the God of all creation, the First Source and Center of all things and beings. First think of God as a creator, then as a controller, and lastly as an infinite upholder. The truth about the Universal Father had begun to dawn upon mankind when the prophet said: “You, God, are alone; there is none beside you. You have created the heaven and the heaven of heavens, with all their hosts; you preserve and control them. By the Sons of God were the universes made. The Creator covers himself with light as with a garment and stretches out the heavens as a curtain.” Only the concept of the Universal Father—one God in the place of many gods—enabled mortal man to comprehend the Father as divine creator and infinite controller.
1:0.2 (21.2) The myriads of planetary systems were all made to be eventually inhabited by many different types of intelligent creatures, beings who could know God, receive the divine affection, and love him in return. The universe of universes is the work of God and the dwelling place of his diverse creatures. “God created the heavens and formed the earth; he established the universe and created this world not in vain; he formed it to be inhabited.”
1:0.3 (21.3) The enlightened worlds all recognize and worship the Universal Father, the eternal maker and infinite upholder of all creation. The will creatures of universe upon universe have embarked upon the long, long Paradise journey, the fascinating struggle of the eternal adventure of attaining God the Father. The transcendent goal of the children of time is to find the eternal God, to comprehend the divine nature, to recognize the Universal Father. God-knowing creatures have only one supreme ambition, just one consuming desire, and that is to become, as they are in their spheres, like him as he is in his Paradise perfection of personality and in his universal sphere of righteous supremacy. From the Universal Father who inhabits eternity there has gone forth the supreme mandate, “Be you perfect, even as I am perfect.” In love and mercy the messengers of Paradise have carried this divine exhortation down through the ages and out through the universes, even to such lowly animal-origin creatures as the human races of Urantia.
1:0.4 (22.1) This magnificent and universal injunction to strive for the attainment of the perfection of divinity is the first duty, and should be the highest ambition, of all the struggling creature creation of the God of perfection. This possibility of the attainment of divine perfection is the final and certain destiny of all man’s eternal spiritual progress.
1:0.5 (22.2) Urantia mortals can hardly hope to be perfect in the infinite sense, but it is entirely possible for human beings, starting out as they do on this planet, to attain the supernal and divine goal which the infinite God has set for mortal man; and when they do achieve this destiny, they will, in all that pertains to self-realization and mind attainment, be just as replete in their sphere of divine perfection as God himself is in his sphere of infinity and eternity. Such perfection may not be universal in the material sense, unlimited in intellectual grasp, or final in spiritual experience, but it is final and complete in all finite aspects of divinity of will, perfection of personality motivation, and God-consciousness.
1:0.6 (22.3) This is the true meaning of that divine command, “Be you perfect, even as I am perfect,” which ever urges mortal man onward and beckons him inward in that long and fascinating struggle for the attainment of higher and higher levels of spiritual values and true universe meanings. This sublime search for the God of universes is the supreme adventure of the inhabitants of all the worlds of time and space.
