Knowledge, of course, a thorough knowledge of all theological science will not make faith, any more than wheels will make a cart. But a certain knowledge is essential, and its absence is fatal to faith. There are the simple ignorant who have forgotten their Catechism and leave the church before the instruction, for fear they might learn something; who never read anything pertaining to religion, who would be ashamed to be detected with a religious book or paper in their hands. Then, there are the learned ignorant, such as our public schools turn out in great numbers each year; who, either are above mere religious knowledge-seeking and disdain all that smacks of church and faith; or, knowing little or nothing at all, imagine they possess a world of theological lore and know all that is knowable. These latter are the more to be pitied, their ignorance doubling back upon itself, as it were. When a man does not realize his own ignorance, his case is well nigh hopeless. If learning cannot give faith, neither can it alone preserve it. Learned men, pillars of the Church have fallen away. Pride, you will say. Yes, of course, pride is the cause of all evil. But we have all our share of it. If it works less havoc in some than in others, that is because pride is or is not kept within bounds. It is necessarily fatal to faith only when it is not controlled by prayer and the helps of practical religion. God alone can preserve our faith. He will do it only at our solicitation. If, therefore, some have not succeeded in keeping the demon of pride under restraint, it is because they refused to consider their faith a pure gift of God that cannot be safely guarded without God's grace; or they forgot that God's grace is assured to no man who does not pray. The man who thinks he is all-sufficient unto himself in matters of religion, as in all other matters, is in danger of being brought to a sense of his own nothingness in a manner not calculated to be agreeable. No man who practised humble prayer ever lost hi& faith, or ever can; for to him grace is assured. And since faith is nothing if not practical, since it is a habit, it follows that irreligion, neglect to practise what we believe will destroy that habit. People who neglect their duty often complain that they have no taste for religion, cannot get interested, find no consolation therein. This justifies further neglect. They make a pretence to seek the cause. The cause is lack of faith; the fires of God's grace are burning low in their souls. They will soon go out unless they are furnished with fuel in the shape of good, solid, practical religion. That is their only salvation. Ignorance, supplemented by lack of prayer and practice, goes a long way in the destruction of faith in any soul, for two essentials are deficient.
