The gophers that drained the water out of the field were not spirits or people; the one thing you have to get rid of is you. Perfect peace does not come from fighting harder; it comes from getting over you and being overcome by Him. Religion is a destroyer and faith is a builder, so stop giving the devil credit and lose faith in him the way you would stop believing a lie. You already have all things that pertain to life and godliness; only your doubt keeps whispering that you are lacking.
