Temptations, limited in their results to the intellectual action, and which do not in any degree take effect in the desires, could not properly be considered temptations, without the physical or natural possibility of a further and sinful action of the mind, without an internal conviction of that possibility, and perhaps we may add, without a distinct sense of danger. Hence, when temptations of this particular character are presented, although they do not take effect in the desires, they are both perceived and felt to be temptations; that is to say, there is a clear perception of their true character, both in themselves and in relation to certain possible results. And in addition to this, there appears to be an instinctive and prompt alarm of the sensitive and moral nature. The desires and affections are not inert and dormant, as some may perhaps suppose; neither are the conscience and the will; but all seem to be penetrated with the sense of imminent hazard, and are thrown into the conscious attitude of repellancy.
