Like Pharaoh did for Joseph; bringing him out of the prison into the palace and making governor over Egypt, God brought us into His Kingdom rid us of all unrighteousness and gave us divine authority.

Over angels: to command help

Over demons; to stop their operation in our lives and the lives of others

Over others; To graciously love them regardless, and at all times

Over ourselves; to walk in self control and not in the lust of the flesh.

This authority works in us through the presence of the His Spirit in us! 

'For God gave us a spirit not of fear but of power and love and self-control': 2 Timothy 1:7
