And let me say, it is perfectly plain that we cannot be clear of the blood of souls unless we have done what we wisely and properly could to prevent their being lost. Of course, if we live in sin ourselves, we are guilty of our own blood; and if we do not do our duty by others we are not clear of their blood. It may be useful to advert, for a moment, to the different classes of duty, which arise out of, and attaches to the various relations in which men stand. Ministers, for instance, are public teachers, and as such they must be "instant in season and out of season;" they must preach the truth, the whole truth, and nothing but the truth; they must lay themselves on the altar and not shun to declare the whole counsel of God. They must not keep back anything that is profitable to their hearers; they must select such truths as they think most needful to be known, and faithfully declare them, and seek zealously to apply them to the hearts and consciences of those to whom they minister; and further, they must live in such a manner as to show that in their own hearts they believe what they preach. They must not think that they will be clear from the blood of souls, merely because they publish the truth with their lips; they must preach also in their temper and life; they must be true and serious teachers in everything. Church officers, deacons, and others, also ought to consider their responsibility: let them remember that it is great; and that they can be clear from the blood of souls only by living in such a manner as to be what they ought to be in every relation which they sustain.
