Spiritual Warfare: 'Prayer + Fasting Overcomes Demonic Forces'

When Jesus saw that the people came running together, He rebuked the unclean spirit, saying to it: “Deaf and dumb spirit, I command you, come out of him and enter him no more!” Then the spirit cried out, convulsed him greatly, and came out of him. … And when He had come into the house, His disciples asked Him privately, ‘Why could we not cast it out?’ So He said to them, ‘This kind can come out by nothing but prayer and fasting.’
