_Thirdly_, The difficulties in which the evidence of religion is involved, which some complain of, is no more a just ground of complaint, than the external circumstances of temptation, which others are placed in; or than difficulties in the practice of it, after a full conviction of its truth. Temptations render our state a more improving state of discipline,[247] than it would be otherwise: as they give occasion for a more attentive exercise of the virtuous principle, which confirms and strengthens it more, than an easier or less attentive exercise of it could. Speculative difficulties are, in this respect, of the very same nature with these external temptations. For the evidence of religion not appearing obvious, is to some persons a temptation to reject it, without any consideration at all; and therefore requires such an attentive exercise of the virtuous principle, seriously to consider that evidence, as there would be no occasion for, but for such temptation. And the supposed doubtfulness of its evidence, after it has been in some sort considered, affords opportunity to an unfair mind of explaining away, and deceitfully hiding from itself, that evidence which it might see; and also for men’s encouraging themselves in vice, from hopes of impunity, though they do clearly see thus much at least, that these hopes are uncertain. In like manner the common temptation to many instances of folly, which end in temporal infamy and ruin, is the ground for hope of not being detected, and of escaping with impunity; _i.e._ the doubtfulness of the proof beforehand, that such foolish behavior will thus end in infamy and ruin. On the contrary, supposed doubtfulness in the evidence of religion calls for a more careful and attentive exercise of the virtuous principle, in fairly yielding themselves up to the proper influence of any real evidence, though doubtful; and in practising conscientiously all virtue, though under some uncertainty, whether the government in the universe may not possibly be such, as that vice may escape with impunity. And in general, temptation, meaning by this word the lesser allurements to wrong and difficulties in the discharge of our duty, as well as the greater ones; temptation, I say, as such and of every kind and degree, as it calls forth some virtuous efforts, additional to what would otherwise have been wanting, cannot but be an additional discipline and improvement of virtue, as well as probation of it in the other senses of that word.[248] So that the very same account is to be given, why the evidence of religion should be left in such a manner, as to require, in some, an attentive, solicitous, perhaps painful exercise of their understanding about it; as why others should be placed in such circumstances, as that the practice of its common duties, after a full conviction of the truth of it, should require attention, solicitude, and pains: or, why appearing doubtfulness should be permitted to
