The expectation of concealment, and therefore of impunity, encourages the great mass of men in the sins which they commit. But you may take the very case in which, of all others, it would seem as though sin had been committed with impunity the case in which a sin is finally pardoned for the sake of the Redeemer and prove with the greatest accuracy of demonstration that nothing can be more unfounded than the expecting to escape all consequences in escaping the first. There is a perfect possibility to use the very lowest word that the man who commits a sin and afterwards repents and is forgiven, may have to bear a burden, through all his after-days on earth, which is distinctly the entailment or consequence of that sin; and with so fatal a power may his transgressions act on every moment of his eternity, that he shall occupy for ever a lower station in the glorified Church than would have been his had the transgression not been wrought.
II. There is something very peculiar in the expression, "evil pursueth the sinner." It is as though it hunted him with the greatest pertinacity, tracking him through the various scenes of life, and then, when perhaps he has all the appearance of having evaded his enemy, and seems, as it were, effectually concealed, the enemy darts upon him suddenly, exacting all its punishment. You cannot think of evil pursuing, and then finding out, a man without thinking of that man as apparently armed against detection: for there is something in the expression which indicates search on the part of the sin, and therefore concealment on the part of the sinner. So that it may be at a moment when there is no remembrance of what has been done, or at least no apprehension of being called to a reckoning, that the crime reappears in the form of vengeance, and proves with what unwearied hostility it has followed the offender.
III. We believe it to be equally true that sins wrought after conversion are not suffered to pass unpunished, however they may be pardoned through the propitiation of Christ. If God is to show displeasure at the iniquities of His own people as well as of His enemies, it must be shown in this life; and hence we suppose it is true that "those whom the Lord loveth He chasteneth," not only because the chastisements prepare for glory, and, therefore, prove love, but also because chastisements are consequences of sin in those whom God loves, and must be experienced on this side of the grave.
