Plain Christians can cast out Satan from their presence by simply resisting him (James 4:7) and his temptations. One of the “signs [that] shall follow them that believe; In My name shall they cast out devils” (Mark 16:17 KJV); but, be warned, in supernatural warfare, sometimes “this kind can come forth by nothing, but by prayer and fasting” (Mark 9:29 KJV). LORD, prepare Thy people for overcoming the Wicked One. Amen and amen.
