=4.= Though the reasonableness of Christianity cannot be shown from analogy, the truth of it may. The truth of a fact may be proved without regard to its quality. The reasonableness of obeying Christianity is proved, if we barely prove Christianity itself to be possible. =5.= Though analogy may not show Christian precepts to be good, it proves them to be credible. IV. _The analogical argument does not remove doubt._ =1.= What opinion does any man hold, about which there can be no doubt? Even the best way of preserving and enjoying this life, is not agreed upon. Whether our measures will accomplish our objects, is always uncertain; and still more whether the objects, if accomplished, will give us happiness. Yet men do not on this account refuse to make exertion. =2.= This objection overlooks the very nature of religion. The embracing of it presupposes a certain degree of candor and integrity, to try which, and exercise, and improve it, is its intention. Just as warning a man of danger, presupposes a disposition to avoid danger. =3.= Religion is a probation, and has evidence enough as such; and would not be such, if it compelled assent. =4.= We never mean by sufficient evidence, such an amount as necessarily determines a man to act, but only such as will show an action to be prudent. V. _As to the small influence of the analogical argument._ =1.= As just observed, religion is a _test_, and an _exercise_, of character; and that some reject it is nothing to our purpose. We are inquiring not what sort of creature man is, but what he should be. This is each man’s own concern. =2.= Religion, as a probation, accomplishes its end, whether individuals believe or not. =3.= Even this objection admits that religion has some weight, and of course it should have some influence; and if so, there is the same reason, though not so strong, for publishing it, that there would be, if it were likely to have greater influence.
