The visions of Hermas continue! A tower is being built with different types of stones. Some of the stones fit together so perfectly that they look like one united piece, and other stones are used from the depths of the waters. Then there's a vision of a great beast known as tribulation that scares Hermas until he remembers what God told him after he had prayed and fasted. These are the visions of Hermas that parallel so much of the Bible and show us where theology was headed for the Christians in Rome.
