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 Spirit to him, but the words in which he declares this revelation to others are taught him by the same Spirit: "which things we also speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth, comparing spiritual things with spiritual." The meaning of these last words is doubtful. They either mean "fitting spiritual words to spiritual truths," or "applying spiritual truths to spiritual people." The sense of the passage is not materially altered whichever meaning is adopted. Paul distinctly affirms that as his knowledge is gained by God's revealing it to him, so his utterance of this knowledge is by the inspiration of God. The spirit of the world produces its philosophies and clothes them in appropriate language. The philosophies with which the Corinthians were familiar taught how the world was made and what man's nature is, and they did so in language full of technicalities and adorned with rhetorical devices. Paul disclaimed this; both his knowledge and the form in which he taught it were dictated, not by the spirit of this world, but by the Spirit of God. The same truths which Paul declared might have been declared in better Greek than he used, and they might have been embellished with illustrative matter and references to their own authors. This style of presenting Divine truth may have been urged upon Paul by some of his Corinthian hearers as far more likely to find entrance into the Greek mind. But Paul refused to allow his style to be formed by human wisdom and the literary methods of secular authors, and thought it more suitable to proclaim spiritual truth in spiritual language and in words which were taught him by the Holy Ghost.
