Or H G Wells who wrote God the Invisible King, which appears to be a very WBTS take on the Kingdom of God. Maybe H G Wells helped Rutherford write books.
Belief in God as the Invisible King brings with it almost necessarily a conception of this coming kingdom of God on earth. Each believer as he grasps this natural and immediate consequence of the faith that has come into his life will form at the same time a Utopian conception of this world changed in the direction of God’s purpose. The vision will follow the realisation of God’s true nature and purpose as a necessary second step. And he will begin to develop the latent citizen of this world-state in himself. He will fall in with the idea of the world-wide sanities of this new order being drawn over the warring outlines of the present, and of men falling out of relationship with the old order and into relationship with the new. Many men and women are already working to-day at tasks that belong essentially to God’s kingdom, tasks that would be of the same essential nature if the world were now a theocracy; for example, they are doing or sustaining scientific research oreducation or creative art; they are making roads to bring men together, they are doctors working for the world’s health, they are building homes, they are constructing machinery to save and increase the powers of men. . . .
Such men and women need only to change their orientation as men will change about at a work-table when the light that was coming in a little while ago from the southern windows, begins presently to comein chiefly from the west, to become open and confessed servants of God. This work that they were doing for ambition, or the love of men or the love of knowledge or what seemed the inherent impulse to the work itself, or for money or honour or country or king, they will realise they are doing for God and by the power of God. Self transformation into a citizen of God’s kingdom and a new realisation of all earthly politics as no more than the struggle to define and achieve the kingdom of God in the earth, follow on, without any need for a fresh spiritual impulse, from the moment when God and the believer meet and clasp one another. This transfiguration of the world into a theocracy may seem a merely fantastic idea to anyone who comes to it freshly without such general theological preparation as the preceding pages have made. But to anyone who has been at the pains to clear his mind even a little from the obsession of existing but transitory things, it ceases to be a mere suggestion and becomes more and more manifestly the real future of mankind.
H G Wells was not a Christian he was a Fabian. The coat of arms of the Fabians used to be a wolf in sheep's clothing. It was surprising to me to see how often H G Wells is quoted in WBTS literature.
