This teaching has to do with God manifesting forth vessels of glory. We are His vessels that He wants to manifest His glory through. He can't do that unless we cooperate. When Jesus turned the water into wine He said that it was done to manifest His glory. But it couldn't have happened without using vessels. Two things happened in that story. Jesus told the servants to fill the vessels and then draw out. We are vessels that God wants to use this book teaches what it takes to fill the vessels as well as what it takes to draw what has been put into them. What is put into the vessel can also be poured out. So, fill your vessel with miraculous power and pour it out to the world.
