THE secret of mathematics is with the mathematician. A child of a few years of age sees columns of figures and a number of rules, and gets a small idea that there is such a thing as the science of mathematics; but it is a dark mystery to the child. It will remain a profound mystery to him until he becomes a mathematician; and even then he may know but very little of the secret, as compared with what may be known. The secret of mathematics is with the mathematician just in proportion to his knowledge of the science of mathematics and his skill in working out the difficult problems of the science. He may possess the secret of ordinary arithmetic, and yet may not possess the secret of algebra; and he may understand the secret of algebra after a while, and yet not understand the secret of geometry during all his life. And yet it may be truly said that he possesses the secret of mathematics. Now “the secret of the Lord is,” as the psalmist says, “with them that fear Him.” Is there anything strange or unreasonable in this assertion?—No; it is one of the most reasonable things in the world. It is the legitimate and logical outcome of a soul’s living and loving relation to his Lord. He who has experienced a real change of heart knows something of Christ which an unconverted person can not know so long as he remains unreconciled to God. No one can understand the love of Christ until he has felt the power of that love throbbing in his soul and prompting him to respond to Christ’s love by grateful adoration and a glad willingness to obey His bidding. But the Christian does not understand the whole secret of his Lord, and never will in this world. And yet what little he does know of it makes him anxious to learn more, and his efforts are rewarded even in this life.—Selected.
