You have the authority of the Kingdom of God backing you. Some believe that God does whatever He wants when He wants, but that is not the case. The Kingdom of God operates as a government with laws. This government is not only enforced by the power of God but also is available for all of His children-and that means you!
On the Cross, Jesus said, "It is finished." We do not need to live in doubt but to live knowing no matter what Satan comes at us with, we have already won.
