We mean not to deny that there is something in this objection. It might even seem to plead the authority of Scripture in its favour--"He that loveth not his brother whom he hath seen, how can he love God whom he hath not seen[38]?" And it was indeed no new remark in Horace's days, Segnius irritant animos demissa per aures, Quam quæ sunt oculis subjecta fidelibus. We receive impressions more readily from visible objects, we feel them more strongly, and retain them more durably. But though it must be granted that this circumstance makes it a more difficult task to preserve the affections in question in a healthful and vigorous state; is it thereby rendered impossible? This were indeed a most precipitate conclusion; and any one who should be disposed to admit the truth of it, might be at least induced to hesitate, when he should reflect that the argument applies equally against the possibility of the love of God, a duty of which the most cursory reader of Scripture, if he admit its divine authority, cannot but acknowledge the indispensable obligation. But we need only look back to the Scripture proofs which have been lately adduced, to be convinced that the religious affections are therein inculcated on us, as a matter of high and serious obligation. Hence we may be assured that the impossibility stated by our Opponent does not exist. Let us scrutinize this matter, however, a little more minutely, and we shall be compelled to acknowledge, though the conclusion may make against ourselves, that the objection vanishes when we fairly and accurately investigate the circumstances of the case. With this view, let us look a little into the nature of the affections of the human mind, and endeavour to ascertain whence it is that they derive their nutriment, and are found from experience to increase in strength.
