=4. God in Nature.=--Sir Isaac Newton, one of the most critical of scientific workers, in writing to his friend Dr. Bentley in 1692, said in reference to the natural universe: "To make such a system, with all its motions, required a Cause which understood and compared together the quantities of matter in the several bodies of the sun and planets, and the gravitating powers resulting from them, the several distances of the primary planets from the sun, and of the secondary ones from Saturn, Jupiter, and the earth; and the velocities with which these planets could revolve about those quantities of matter in the central bodies; and to compare and adjust all these things together in so great a variety of bodies argues the Cause to be not blind and fortuitous, but very well skilled in mechanics and geometry." =5. Natural Indications of God's Existence.=--"It may not be, it is not likely, that God can be found with microscope and scalpel, with test-tube or flask, with goniometer or telescope; but with such tools, the student earnestly working, cannot fail to recognize a power beyond his vision, yet a power of which the pulses and the motions are unmistakable. The extent of our solar system once seemed to man more limited than it does at present; and the discovery of the most distant of the planetary family was due to a recognition of an attractive force inexplicable except on the supposition of the existence of another planet. The astronomer, tracing known bodies along their orbital paths, could feel the pull, could see the wire that drew them from a narrower course; he saw not Neptune as he piled calculations sheet on sheet; but the existence of that orb was clearly indicated, and by heeding such indications he sought for it, and it was found. Theory alone could never have revealed it, though theory was incomplete, unsatisfactory without it; but the practical search, instigated by theory, led to the great demonstration. And what is all science but theory compared to the practical influence of prayerful reliance on the assistance of an omnipotent, omniscient power? Disregard not the indications of your science work,--the trembling of the needle that reveals the magnetic influence; the instinct within that speaks of a life and a Life-Giver, far beyond human power of explanation or comprehension. As you sit beneath the canopied vault, pondering in the silence of night over the perturbations, the yearnings which the soul cannot ignore, turn in the direction indicated by those impulses, and with the penetrating, space-annihilating, time-annulling glass of prayer and faith, seek the source of that pervading force."--The Author in _Baccalaureate Sermon_, Utah University Quarterly, Sept., 1895.
