Power never was and never will be the issue between God and Satan. Authority was the issue - the authority Satan had obtained through Adam. Jesus did not come to get back any power, nor to remove Satan's power. He came to regain the authority Adam lost to the serpent and break his headship over the earth. …. Authority is the issue. Power does the work, but authority controls the power. Dutch Sheets (The power issue was won in heaven by God before man was created, and won on earth at the cross.)
