The bible records at least 60 times where God has instructed his people to fear not. We are even told in 2 Tim. Fear is not from God. If it is not from God, then it is from Satan. We know that faith comes by hearing and hearing by the word of God.
Fear also comes by hearing, but it is hearing the lies of Satan.
Fear has an active partner, worry. When fear grabs us, worry sets in. Just as fear is perverted faith, worry is perverted meditation. It is meditation on the lies of the devil. God has provided a way for us to get rid of fear.
