Whatever you don’t believe you have authority over, you are afraid of. Whenever you encounter fear, stop and ask the Lord to give you authority over it and the fear will subside. Jesus feared nothing because He had authority over everything. Don’t forget Christ is in you, so through Him you can have authority over everything that scares you.
Matthew 28:18 “Jesus came up and spoke to them, saying, “All authority has been given to Me in heaven and on earth.”
