Luke 11:20

Overview - Luke 11
Christ teaches us to pray, and that instantly;
11 assuring us that God will give all good things to them that ask him.
14 He, casting out a dumb devil, rebukes the blasphemous Pharisees;
27 and shows who are blessed;
29 preaches to the people;
37 and reprehends the outward shew of holiness in the Pharisees, scribes, and lawyers.

Luke 11:20  (King James Version)
But if I with the finger of God cast out devils, no doubt the kingdom of God is come upon you.

the finger
Exodus 8:19 ; Matthew 12:28

the kingdom
For the destruction of the kingdom of Satan plainly implies the setting up of the kingdom of God. The reasoning of the Pharisees (ver. 17, ; and Matthew 12:24 ,25,) was not expressed, and Jesus knowing their thoughts, gave ample proof of his omniscience. This, with our Lord's masterly confutation of their reasonings, by a conclusion drawn from their own premises, one would have supposed might have humbled and convinced those men; but the most conclusive reasoning, and the most astonishing miracles, were lost upon a people who were obstinately determined to disbelieve every thing that was good relative to Jesus of Nazareth.
