The authority of the believer is unveiled more fully in the Book of Ephesians than any other epistle written to the churches. Because this book is based on Ephesians, let me encourage you to read the first three chapters over and over again for several days.
You will notice there are Spirit-anointed prayers at the end of the first and third chapters. However, Paul didn't pray these prayers only for the Church at Ephesus. These prayers apply to us today just as much as they did to the believers at Ephesus, because they were given by the Holy Spirit.
