Fear: a distressing emotion aroused by impending danger, evil, pain, etc., whether the threat is real or imagined; the feeling or condition of being afraid.
Read that again. Whether the threat is real or imagined is what it says. Fear usually comes in areas imagined correct? Fear is nothing but something that the king of lies feeds you with. The devil just wants you to be scared.
2 Timothy 1:7 says For God has not given us a spirit of fear, but of power and of love and of a sound mind. You see, fear will do nothing if you don't let it. You have to face your fears to accomplish. Don't let fears make you miss out on a fun or important moment. The moment you fall to fear, the devil will just use it over and over again.
All you have to do to stop this is pray to The Lord. Pray to him and tell him how you feel from your heart. Ask him to lead you in your actions. But also rebuke the devil in the name of Jesus. Repeat that over and over out loud. Then, nothing can touch you.
