Charles Spurgeon Commentary Luke 11:20-22

"But if I by the finger of God cast out demons, then is the kingdom of God come upon you. When the strong [man] fully armed guardeth his own court, his goods are in peace: but when a stronger than he shall come upon him, and overcome him, he taketh from him his whole armor wherein he trusted, and divideth his spoils." — Luke 11:20-22 (ASV)

But if I with the finger of God cast out devil, no doubt the kingdom of God is come upon you. When a strong man armed keeps his palace, his goods are in peace: but when a stronger than he shall come upon him and overcome him, he takes from him all his armor in which he trusted, and divides his spoils.

This is how Christ drives out the devil: by sheer force of arms, he overcomes him and drives him out. He does not cajole him, invite him, or persuade him to go; but he fights with him, puts forth his omnipotent power against him, overthrows him, takes away his armor, and divides the spoil. Were you ever conscious of Hugh's fight like that? If not, be afraid of your so-called reformation, for there is no true reformation, and no true conversion, in which there is no conflict between Christ and Satan.
