While I do appreciate the Speaker's belief in Christ, I do get a little concerned when people start talking about tying and binding as regard to Satan and demons.
We don't see that kind of approach in Scripture. We are to resist the enemy for sure.
I believe that they take it from this passage:
Mark 3:27
21st Century King James Version
27 No man can enter into a strong man’s house and despoil his goods, unless he will first bind the strong man; and then he will despoil his house.
