And then shall be fulfilled the great words of prophecy, which men have read so long with hope darkened by despair: “The earth shall be full of the knowledge of the Lord, as the waters cover the sea”; “it shall come that I will gather all nations and tongues, and they shall come and see my glory.”[180] The promises of Christianity, in harmony with the promises of Science, and more beautiful still, will become the realities of earth; and that precious example wherein is the way of life will be another noon-day sun for guidance and safety. * * * * * The question _How?_ is followed by that other question _When?_ The answer is easy. Not at once; not by any sudden conquest; not in the lifetime of any individual man; not in any way which does not recognize Nature as co-worker. It is by constant, incessant, unceasing activity in conformity with law that Nature works; and so in these world-subduing operations Man can be successful only in harmony with Nature. Because in our brief pilgrimage we are not permitted to witness the transcendent glory, it is none the less certain. The peaceful conquest will proceed, and every day must contribute its fruits. At the beginning of the last century Russia was a barbarous country, shut out from opportunities of improvement. Authentic report attests its condition. Through contact with Europe it was vitalized. The life-giving principle circulated, and this vast empire felt the change. Exposed to European contact at one point only, here the influence began; but the native energies of the people, under the guidance of a powerful ruler, responded to this influence, and Russia came within the widening circle of European civilization. Why may not this experience be repeated elsewhere, and distant places feel the same beneficent power?
