Luke 11:20-23

But if I drive out the demons by the finger of God, then the kingdom of God has already come upon you. When the strong man, fully armed, guards his own house, his belongings are undisturbed and secure. But when someone stronger than he attacks and overpowers him, he robs him of all his armor on which he had relied and divides his [goods as] spoil. He who is not with Me [believing in Me as Lord and Savior] is against Me [there is no impartial position]; and he who does not gather with Me [assisting in My ministry], scatters.
