God, that is to say, is the true Sun, the true Origin of all Lights, the true bestower of every good and perfect gift. The word rendered "variableness," is a technical word, used by ourselves in modern English as "parallax," and employed in the Septuagint Version to denote the revolutions of the heavenly bodies, described in the thirty-eighth chapter of the book of Job, as "the ordinances of the heavens." With the natural sun, therefore, there is "variableness," that is to say, real or apparent change of place; there is none with God. Neither is there with Him any darkness of eclipse; any "shadow" caused as in the case of the material sun, by the "turning" of earth and moon in their orbits. The knowledge of "the alternations of the turning of the sun," described in the Book of Wisdom as a feature of the learning of Solomon, was a knowledge of the laws of this "variableness" and "turning"; especially of the "turning" of its rising and setting points at the two solstices; and St. James may well have had that passage in his mind when he wrote. For Science deals with the knowledge of things that change, as they change, and of their changes, but Faith with the knowledge of Him that abideth for ever, and it is to this higher knowledge that St. James wished to point his readers. Science deals with the knowledge of things that change, as they change and of their changes. The physical facts that we have learned in the last years about that changeful body the sun are briefly these:-- Its core or inner nucleus is not accessible to observation, its nature and constitution being a mere matter of inference. The "photosphere" is a shell of incandescent cloud surrounding the nucleus, but the depth, or thickness of this shell is quite unknown. The outer surface--which we see--of the photosphere is certainly pretty sharply defined, though very irregular, rising at points into whiter aggregations, called "faculæ," and perhaps depressed at other places in the dark "spots." Immediately above the photosphere lies the "reversing layer" in which are found the substances which give rise to the gaps in the sun's spectrum--the Fraunhofer lines. Above the "reversing layer" lies the scarlet "chromosphere" with "prominences" of various forms and dimensions rising high above the solar surface; and over, and embracing all, is the "corona," with its mysterious petal-like forms and rod-like rays.
