1. The Spirit of God alone knows the mind of God and searches its deep things, just as none but the spirit of man which is in him knows the things of man. "There is in every man a life hidden from all eyes, a world of impressions, anxieties, aspirations, and struggles, of which he alone, in so far as he is a spirit--that is to say, a conscious and personal being--gives account to himself. This inner world is unknown to others, except in so far as he reveals it to them by speech."[3] And if we are baffled often and deceived regarding human character and find ourselves unable to penetrate to the "deep things" of man, to his inmost thoughts and motives, much more is it true that "the deep things" of God are wholly beyond our ken and are only known by the Spirit of God which is in Him. A vague and uncertain guess, possibly not altogether wrong, probably altogether wrong, is all we can attain to. [3] Godet. And still more certainly true is this of God's _purposes_. Even though you flatter yourself you know a man's nature, you cannot certainly predict his intentions. You cannot anticipate the thoughts of an able man whom you see designing a machine, or planning a building, or conceiving a literary work; you cannot say in what form a vindictive man will wreak his vengeance; nor can you penetrate through the abstracted look of the charitable and read the precise form his bounty will take. Every great work even of man comes upon us by surprise; the various inventions that facilitate business, the new poems, the new books, the new works of art, have never been conceived before. They were hidden mysteries until the originating mind disclosed them. And much more were God's intentions and His method of accomplishing inconceivable by any but Himself. What God's purpose was in creating man, what He designed to accomplish through the death of Christ, what was to be the outcome of all human life, and temptation, and struggle--these things were God's secret, known only to the Spirit of God that was in Him. 2. This Spirit, Paul declares, was given to him, and revealed to him God's purposes, "the things which are freely given to us of God." He had received "not the spirit of the world," which would have enabled him only to theorize, and speculate, and create another "wisdom of this world;" but he had received "the Spirit which is of God," and this Spirit had revealed to him "the things which God hath prepared for them that love Him."
