How can one enter into a strong man’s house. — The parable implied in the question appears in a fuller form in Luke 11:21-22. Here it will be enough to note that the “strong man” is Satan. The “house” is the region which is subject to him — i.e., either the world at large, or the spirits of individual men; the “goods” or “instruments” (comp. the “armour” of Luke 11:22) are the demons or subordinate powers of evil by which he maintains his dominion; the “binding of the strong man” is the check given to the tyranny of Satan by emancipating the possessed sufferers from their thraldom; the “spoiling of the house” implies the final victory over him.
