Sadly, many today have the spirit of fear. The spirit of fear has people putting bars on homes, alarm systems, carrying weapons, taking medication and doing all sorts of other things to protect themselves and their families. These things are good for protection but not good when done out of a spirit of fear. God has given us a spirit of love. If he lives inside of us we have that spirit of love.
Perfect love casts out all fear.
That means love replaces fear. It terminates the fear in our lives. There is no fear in love. If you fear you are not perfect in love. He has given us a spirit of power.
