2 Timothy 1:7- For God hath not given us the spirit of fear, but of power, and of love, and of a sound mind.
This Scripture lets us know that first of all fear is a spirit! And second that God did not give it to us. When we come into the revelation of this truth, we can cast fear out in the name of Jesus because we believe and know that it is not of Him according to His Word and that it may be present in our lives but it has to go. When you are feeling fearful of anything, it is letting you know that, that spirit is present around you even though you can not see it.
Pray that spirit away (cast it out) in the Name of Jesus!
