We think the “burglar” in this little parable is the bad-guy and the householder is the good-guy, but the whole context turns that on its head. The “householder” is the strong-man (as he is called in a parallel passage) who invaded the house and usurped the property of the rightful owner. It is the Satan who has done this to the beautiful world God created. The “burglar” is the rightful owner coming back to claim his own. That is why Jesus says “he will come like a thief in the night”.
