Many of you, by the bad examples you have set, by corrupting the minds of others, by your sinful conversation, by leading them into, or strengthening them into sin, and by the mischief you have done in human society other ways that might be mentioned, have been guilty of those things that have tended to others' damnation.  You have heretofore appeared on the side of sin and Satan, and have strengthened their interest, and have been many ways accessary to others' sins, have hardened their hearts, and thereby have done what has tended to the ruin of their souls.  Without doubt there are those here present who have been in a great measure the means of others' damnation.  One man may really be a means of others' damnation as well as salvation.
