Besides, faith is meritorious, and in order to merit one must do something difficult and be free to act. The difficulty is to believe what we cannot understand, through pride of intelligence, and to bring that stiff domineering faculty to recognize a superior. The difficulty is to bend the will to the acceptance of truths, and consequent obligations that gall our self-love and the flesh'. The believer must have humility and self-denial. The grace of God follows these virtues into a soul, and then your act of faith is complete. Herein we discover the great wisdom of God who sets the price of faith, and of salvation that depends on it, not on the mind, but on the will; not on the intelligence alone, but on the heart. To no man is grace denied. Every man has the will to grasp what is good. But though to all He gives a will, all have not the same degree of intelligence; He does not endow them equally in this respect. How then could He make intelligence the first principle of salvation and of faith? God searches the heart, not the mind. A modicum of wit is guaranteed to all to know that they can safely believe. Be one ever so unlettered and ignorant, and dull, faith and heaven are to him as accessible as to the sage, savant and the genius. For all, the way is the same. CHAPTER XXI. HOW WE BELIEVE. FAITH is the edifice of a Christian life. It is, of itself, a mere shell, so to speak, for unless good works sustain and adorn it, it will crumble, and the Almighty in His day will reduce it to ashes; faith without works is of no avail. The corner stone of this edifice is the authority of the word of God, while His gratuitous grace, our intelligence and will furnish the material for building. Now, there are three features of that spiritual construction that deserve a moment's consideration. First, the edifice is solid; our faith must be firm. No hesitation, no wavering, no deliberate doubting, no suspicion, no take-and-leave. What we believe comes from God, and we have the infallible authority of the Church for it, and of that we must be certain. That certainly must not for a moment falter, and the moment it does falter, there is no telling but that the whole edifice so laboriously raised will tumble down upon the guilty shoulders of the imprudent doubter.
