170:4.14

This world has never seriously or sincerely or honestly tried out these dynamic ideas and divine ideals of Jesus’ doctrine of the kingdom of heaven. But you should not become discouraged by the apparently slow progress of the kingdom idea on Urantia. Remember that the order of progressive evolution is subjected to sudden and unexpected periodical changes in both the material and the spiritual worlds. The bestowal of Jesus as an incarnated Son was just such a strange and unexpected event in the spiritual life of the world. Neither make the fatal mistake, in looking for the age manifestation of the kingdom, of failing to effect its establishment within your own souls.
