And in accordance with this view, we may very properly, sincerely, and deeply mourn over those various infirmities and imperfections, which flow out of our connection with an erring and fallen parent, although they are very different in their nature from deliberate and voluntary transgressions; and may with deep humility make application to the blood of Christ, as alone possessing that atoning efficacy, which can wash their stains away. In other words, God is to be regarded as righteous in exacting from us whatever we could or might have rendered him if Adam had not fallen, and if the race had remained holy. Nevertheless he has mercifully seen fit to remit or forgive all these involuntary sins, more commonly and perhaps more justly called imperfections or trespasses, if we will but cordially accept of the atonement in the blood of Christ. But without the shedding of blood and confession, there is no more remission in this case than in any other. It is probably in reference to such imperfections or trespasses, rather than to sins of a deliberate and voluntary nature, that some good people speak of the moral certainty or necessity we are under of sinning all the time. If such is all their meaning, it is not very necessary to dispute with them.
