Actually, pastors and priests have testified that the room temp gets very cold. Reptiles sleep in the cold. Worship and praise to God will send them away unless already possessing. What did the demon say to the guy who tried to expel it? [Don't try this at home and make sure Jesus knows you and you know Him before you use the most powerful name in the universe]
Acts 19
11 God was performing extraordinary miracles by the hands of Paul,
12 so that handkerchiefs or aprons were even carried from his body to the sick, and the diseases left them and the evil spirits went out.
13 But also some of the Jewish exorcists, who went from place to place, attempted to name over those who had the evil spirits the name of the Lord Jesus, saying, “I adjure you by Jesus whom Paul preaches.”
14 Seven sons of one Sceva, a Jewish chief priest, were doing this.
15 And the evil spirit answered and said to them, “I recognize Jesus, and I know about Paul, but who are you?” 16 And the man, in whom was the evil spirit, leaped on them and subdued all of them and overpowered them, so that they fled out of that house naked and wounded. 17 This became known to all, both Jews and Greeks, who lived in Ephesus; and fear fell upon them all and the name of the Lord Jesus was being magnified.
