Matthew 10:1 (NLT2) 1 Jesus called his twelve disciples together and gave them authority to cast out evil spirits and to heal every kind of disease and illness.
Demons are very cowardly, always anxious about the fire that has been prepared for them. To bolster your courage against them, take this sure sign: When some apparition occurs, do not collapse in terror, But whatever it may be ask first, bravely, "Who are you, and where do you come from?" If it is a divine vision, it will give you assurances and change your fear to joy. If it is some devil, it will immediately be weakened by your formidable spirit. —Antony of Egypt
