Matthew 15:21-28 describes an encounter between Jesus and a Canaanite woman.
And Jesus went away from there and withdrew to the district of Tyre and Sidon. And behold, a Canaanite woman from that region came out and was crying, “Have mercy on me, O Lord, Son of David; my daughter is severely oppressed by a demon.”
Once three men went on an ocean cruise. One of them was an athlete who was in top physical condition and was a champion swimmer. The second knew how to swim and occasionally exercised but generally didn’t attach much importance to keeping fit. The third was a couch potato who didn’t know how to swim and was too lazy to ever exercise. There were plenty of things they could do on the ship to occupy their time and they became so interested in these activities that they didn’t bother to keep track of where the ship was.
In Mark 16:17,18 Jesus tells his disciples of signs that will accompany those who believe.
And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; they will pick up serpents with their hands; and if they drink any deadly poison, it will not hurt them; they will lay their hands on the sick, and they will recover.
