Moreover, the earth, which is here the type of the man, "bringeth forth fruit of herself." We must mind what we are at in expounding this, for human hearts do not produce faith of themselves; they are as hard rock on which the seed perishes. But it means this--that as the earth under the blessing of the dew and the rain is, by God's secret working upon it, made to take up and embrace the seed, so the heart of man is made ready to receive and enfold the gospel of Jesus Christ within itself. Man's awakened heart wants exactly what the word of God supplies. Moved by a divine influence the soul embraces the truth, and is embraced by it, and so the truth lives in the heart, and is quickened by it. Man's love accepts the love of God; man's faith wrought in him by the Spirit of God believes the truth of God; man's hope wrought in him by the Holy Ghost lays hold upon the things revealed, and so the heavenly seed grows in the soil of the soul. The life comes not from you who preach the word, but it is placed within the word which you preach by the Holy Spirit. The life is not in your hand, but in the heart which is led to take hold upon the truth by the Spirit of God. Salvation comes not from the personal authority of the preacher, but through the personal conviction, personal faith, and personal love of the hearer. So much as this we may know, and is it not enough for all practical purposes? Still, there is _a something which we cannot know_, a secret into which we cannot pry. I repeat what I have said before: you cannot look into men's inward parts and see exactly how the truth takes hold upon the heart, or the heart takes hold upon the truth. Many have watched their own feelings till they have become blind with despondency, and others have watched the feelings of the young till they have done them rather harm than good by their rigorous supervision. In God's work there is more room for faith than for sight. The heavenly seed grows secretly. You must bury it out of sight, or there will be no harvest. Even if you keep the seed above ground, and it does sprout, you cannot discover _how_ it grows; even though you microscopically watched its swelling and bursting, you could not see the inward vital force which moves the seed. Thou knowest not the way of the Spirit. His work is wrought in secret. "Explain the new birth," says somebody. My answer is, "Experience the new birth, and you shall know what it is." There are secrets into which we cannot enter, for their light is too bright for mortal eyes to endure. O man, thou canst not become omniscient, for thou art a creature, and not the Creator. For thee there must ever be a region not only unknown but unknowable. So far shall thy knowledge go, but no farther; and thou mayest thank God it is so, for thus he leaves room for faith, and gives cause for prayer. Cry mightily unto the Great Worker to do what thou canst not attempt to perform, that so, when thou seest men
