2. In the cases of sudden conversion I have been speaking of, when men change at once either from open sin, or again from the zealous partizanship of a certain creed, to some novel form of faith or worship, their light-mindedness is detected by their frequent changing--their changing again and again, so that one can never be certain of them. This is the test of their unsoundness;--having no root in themselves, their convictions and earnestness quickly wither away. But there is another kind of sudden conversion, which I proceed to mention, in which a man perseveres to the end, consistent in the new form he adopts, and which may be right or wrong, as it happens, but which _he_ cannot be said to recommend or confirm to us by his own change. I mean when a man, for some reason or other, whether in religion or not, takes a great disgust to his present course of life, and suddenly abandons it for another. This is the case of those who rush from one to the other extreme, and it generally arises from strong and painful feeling, unsettling and, as it were, revolutionizing the mind. A story is told of a spendthrift who, having ruined himself by his extravagances, went out of doors to meditate on his own folly and misery, and in the course of a few hours returned home a determined miser, and was for the rest of his life remarkable for covetousness and penuriousness. This is not more extraordinary than the fickleness of mind just now described. In like manner, men sometimes will change suddenly from love to hatred, from over-daring to cowardice. These are no amiable changes, whether arising or not from bodily malady, as is sometimes the case; nor do they impart any credit or sanction to the particular secular course or habit of mind adopted on the change: neither do they in religion therefore. A man who suddenly professes religion after a profligate life, merely because he is sick of his vices, or tormented by the thought of God's anger, which is the consequence of them, and without the love of God, does no honour to religion, for he might, if it so chanced, turn a miser or a misanthrope; and, therefore, though religion is not at all the less holy and true because he submits himself to it, and though doubtless it is a much better thing for _him_ that he turns to religion than that he should become a miser or a misanthrope, still, when he acts on such motives as I have described, he cannot be said to do any honour to the cause of religion by his conversion. Yet it is such persons who at various times have been thought great saints, and been reckoned to recommend and prove the truth of the Gospel to the world!
