Paul then used two methods of teaching. In addressing those who had yet to be won to Christ, he used the foolishness of preaching, and presented to them the Cross of Christ. In addressing those who had already owned the power of the Cross and made some growth in Christian knowledge and character, he enlarged upon the significance of the Cross and the light it threw on all moral relations, on God and on man. And even in this department of his work he disclaims any desire to propagate a philosophy of his own. The system of truth he proclaims to the Christian people is not of his own devising. It is not in virtue of his own speculative ability he has discovered it. It is not one of the wisdoms of this world, having its origin in the brain of an ingenious theorist. On the contrary, it has its origin in God, and partakes therefore of the truth and stability attaching to the thoughts of God.
II. But if it be undiscoverable by man, how does Paul come to know it? To the Corinthian intelligence there seemed but these three ways of learning anything: seeing, hearing, or thinking; and if God's wisdom was attainable by none of these, how was it reached? Paul proceeds to show how he was enabled to "speak" this wisdom. He does this in vers. 10-13, in which his chief affirmations are that the Spirit of God alone knows the mind of God, that this Spirit has been given to him to reveal to him God's mind and to enable him to divulge that mind to others in suitable words.
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.
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."
We may think of revelation either as the act of God or as it is received by man. God reveals Himself in all He does, as man discloses his character in all he does. With God's first act therefore in the remotest past revelation began. As yet there was none to receive the knowledge of God, but God showed His nature and His purpose as soon as He began to do anything. And this revelation of Himself has continued ever since. In the world around us and the earth on which we live God reveals Himself; "the things which are made," as Paul says, "give us clearly to see and understand the invisible things of God, His unseen nature, from the creation of the world." Still more fully is God's nature revealed in man: in conscience, distinguishing between right and wrong; in the spirit craving fellowship with the Eternal. In the history of nations, and especially in the history of that nation which founded itself upon its idea of God, He revealed Himself. By guiding it, by delivering it from Egypt, by punishing it, God made Himself known to Israel. And at length in Jesus Christ God gave the fullest possible manifestation of Himself. The veil was entirely lifted, and God came as much as possible into free intercourse with His creatures. He put Himself within reach of our knowledge.
But it was not enough that God be revealed objectively in Christ; there must also be a subjective revelation within the soul of the beholder. It was not enough that God be manifested in the flesh and men be allowed to draw such inferences as they could from that manifestation; but, in addition to this, God gave His Spirit to Paul and others that they might see the full significance of that manifestation. It was quite possible for men to be witnesses of the objective revelation without understanding it. The open eye is needed as well as outward light. And Paul everywhere insists upon this: that he had received his knowledge of Divine truth by revelation, not by the mere exercise of his own unaided thought, but by a spiritual enlightenment through the gift of God's Spirit.
The presence of God's Spirit in any man can of course only be verified by the results. God's Spirit working in and by means of man's nature cannot be known in separation from the man's spirit and the work done in that spirit. This inward revelation which Paul refers to is accomplished by the action of the Divine Spirit on the human faculties, quickening and elevating these faculties. The revelation or new knowledge acquired by Paul was given by God, but at the same time was acquired by Paul's own faculties, so that it remained with him always, just as the knowledge we naturally acquire remains with us and can be freely used by us. An inward revelation can come to a man only in the form of impressions, convictions, thoughts arising in his own mind. Paul knew that his knowledge was a revelation of God, not by the suddenness with which it was imparted, not by supernatural appearances accompanying it, not by any sense or consciousness of another Spirit working with his own, but by the results. It is always the substance or contents of any revelation which proves its origin. Paul knew he had the mind of Christ because he found that he could understand Christ's words and work, could perfectly sympathize with His aims and look at things from Christ's point of view.
In their humility, many persons shrink from making this affirmation here made by Paul; they cannot ever unhesitatingly affirm that the Spirit of God is given them or that they have the mind of Christ. Such persons should recognise that it was the very humility of Paul which enabled him so confidently to affirm these things of himself. He knew that the knowledge of Christ's purposes he had and the sympathy with them were the evidence of God's Spirit working in him. He knew that without God's Spirit he himself could never have had these thoughts. And it is when we recognise our own insufficiency most that we are readiest to confess the presence of God's Spirit.
3. But Paul makes a further affirmation. Not only is the knowledge he has of Divine things a revelation made by God's
