I was involved deeply in witchcraft and the occult before turning to Christ, and have cast spells on people. Did they work? The people did get sick, but they weren't Christians and didn't know Christ. They were open. An empty vessel waiting to be filled. If someone is sending demons against these ladies, and they are true believers, they have nothing to fear..as long as they stand on the power of Christ and rebuff it. I truly believe that the devil can only get to us if we allow him to. We don't have to stand idly by and let it happen. Rebuke/resist the devil and he will flee from you. Pray, give thanks to the Lord...this is how we fight back. Make no mistake....we are at war here, and they need to fight back.
