When God commissions leaders, as He did with Joshua, He releases mantles over them. These mantles give them the supernatural ability to complete their mission. Unlike the gifts and calls of God that remain on a person for life, a mantle stays with the mission, not with the man or woman. For example, anyone who becomes president of the United States must be very gifted. A person does not rise to the highest office in our land without that qualification. But on Inauguration Day, something powerful takes place in the spirit realm; a presidential mantle from heaven is given to that person. God never grants someone an assignment without giving him or her the ability to complete it.
