Force of Faith by Kenneth Copeland
People have the mistaken idea that the world of the spirit is an unreal, unreasonable, unsanctioned, and unregulated world where you never know what will happen. This is not true. The world of the spirit is God’s realm, and the world of the natural is controlled by the world of the spirit. God is a spirit. Jesus said that those that worship Him must worship Him in Spirit and in truth. The authority of the spiritual world was given to Jesus when He was raised from the dead; this world is lorded over by Jesus of Nazareth. Believers have been given His name to operate in authority here in the earth. God, a spirit, created all matter, so the world of the spirit is more real and powerful than the world of the natural, physical, see-and-be-seen world.
