As the ancient philosopher Heraclitus reminded us. It is not possible to step a second time in the same river. For the river keeps moving and the second step will be into different water. Moses was a great leader because he brought the people out of slavery in Egypt and across the Red Sea. He held them together in the wilderness and after a generation deposited them at the edge of the Promised Land.
Leaders lead people, and they have a vision of where they want to go.
They can see a world in which peace and justice are possibilities, a world in which the lion and the lamb can lie down together in harmony, and they paint this vision in such vivid colors that others want to follow them. That's one of the corollaries. It's simple enough, but again, it's frequently overlooked. There will always be people who claim to be leading when all they do is stand on the sideline, screaming and complaining. Leadership doesn't just diagnose the problems of the present.
