Now there is no more conspicuous instance of this law, than that which is afforded by the preaching of the Gospel of God. God's Word, as Christ reminds us, does not fall on virgin soil; it falls on soil already holding other seed. When a preacher stands up with the Word of God in a great congregation, vast as Scripture warrants us for believing his power to be, his is not the only power that is operative. Each man present has a life behind that hour and place, lying away in the darkness, silent and dead as far as the congregation are concerned, but in his own heart as vivid and loud as the voice of the preacher, though he be preaching never so forcibly. The prophet is not the only power in the delivery of God's Word, nor is the Holy Spirit the only power. That would make all preaching of the Word a mere display. But the Bible represents it as a strife. And now it is said of men themselves that they harden their hearts against the Word, and now--because such hardening is the result of previous sinning, and has therefore a judicial character--that God hardens their hearts. _Simon, Simon_, said Christ to a face that spread out to His own all the ardour of worship, _Satan is desiring to have you, but I have prayed that your faith fail not_. God sends His Word into our hearts; the Mediator stands by, and prays that it make us His own. But there are other factors in the operation, and the result depends on our own will; it depends on our own will, and it is dreadfully determined by our habits.
Now this is one of the first facts to which a young reformer or prophet awakes. Such an awakening is a necessary element in his education and apprenticeship. He has seen the Lord high and lifted up. His lips have been touched by the coal from off the altar. His first feeling is that nothing can withstand that power, nothing gainsay this inspiration. Is he a Nehemiah, and the hand of the Lord has been mighty upon him? Then he feels that he has but to tell his fellows of it to make them as enthusiastic in the Lord's work as himself. Is he a Mazzini, aflame from his boyhood with aspirations for his country, consecrated from his birth to the cause of duty? Then he leaps with joy upon his mission; he has but to show himself, to speak, to lead the way, and his country is free. Is he--to descend to a lower degree of prophecy--a Fourier, sensitive more than most to how anarchic society is, and righteously eager to settle it upon stable foundations? Then he draws his plans for reconstruction, he projects his phalanges and phalansteres, and believes that he has solved the social problem. Is he--to come back to the heights--an Isaiah, with the Word of God in him like fire? Then he sees his vision of the perfect state; he thinks to lift his people to it by a word. _O house of Jacob_, he says, _come ye, and let us walk in the light of the Lord_!
For all of whom the next necessary stage of experience is one of disappointment, with the hard commission, _Make the heart of this people fat_. They must learn that, if God has caught themselves young, and when it was possible to make them entirely His own, the human race to whom He sends them is old, too old for them to effect much upon the mass of it beyond the hardening and perpetuation of evil. Fourier finds that to produce his perfect State he would need to re-create mankind, to cut down the tree to the very roots, and begin again. After the first rush of patriotic fervour, which carried so many of his countrymen with him, Mazzini discovers himself in "a moral desert," confesses that the struggle to liberate his fatherland, which has only quickened him to further devotion in so great a cause, has been productive of scepticism in his followers, and has left them withered and hardened of heart, whom it had found so capable of heroic impulses. He tells us how they upbraided and scorned him, left him in exile, and returned to their homes, from which they had set out with vows to die for their country, doubting now whether there was anything at all worth living or dying for outside themselves. Mazzini's description of the first passage of his career is invaluable for the light which it throws upon this commission of Isaiah. History does not contain a more dramatic representation of the entirely opposite effects of the same Divine movement upon different natures. While the first efforts for the liberty of Italy materialized the greater number of his countrymen, whom Mazzini had persuaded to embark upon it, the failure and their consequent defection only served to strip this heroic soul of the last rags of selfishness, and consecrate it more utterly to the will of God and the duty that lay before it.
