The culmination of King Benjamin’s address to his people was the “mighty change” they experienced which led them to repent and covenant to keep the commandments and to seek to do good continually. While the scripture says that they “had no more disposition to do evil,” given the later history of this people, we might surmise that the disposition didn’t last. Nor did Benjamin expect that his people would remain sinless, but instead they would likely need a disposition to seek and obtain forgiveness. I suspect that one aspect of the “mighty change” described in the Book of Mormon is exactly that, seeking forgiveness for errors and sin.
King Benjamin’s oft-cited dictum that service to our fellow man is service to God is well known among Mormons. And, if surveys like the recent University of Pennsylvania survey are accurate, Mormons do quite well putting the idea in practice. Still, better than others doesn’t mean that we are where we should be or ought to be. And, like all humans, we have our rationales for failure to act. So perhaps a poem that addresses our failures will work well with Book of Mormon lesson #15.
