It seems likely that today we (in most western democracies) aren’t influenced by leaders the same way that the children of Israel were by their kings (at least as described in Old Testament Gospel Doctrine lesson #27). I suspect that all else being equal, democracy reduces the influence of individual leaders. Still, the example of the influence of their rulers, for good or evil, is instructive today. And the following poem highlights the qualifications of leaders and how their influence is felt by those that they lead.
As the Children of Israel entered the promised land, they also faced a change of leadership, with all that entails. As Moses doesn’t cross the Jordan, Joshua is called to lead the Israelites, cross the Jordan and subjugate the territory promised. Lesson 18 of the Old Testament Gospel Doctrine manual portrays this time as a time when the Children of Israel re-commit themselves to serving the Lord behind a new leader. Following the death of Joseph Smith, the nascent Mormon people also had to face a change in leadership, and (although in a somewhat different manner) cross a river behind that leader on their way into a new land. Their similarity to the ancient Israelites was not lost on them, and influenced the following poem.
