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”.
The coming together of the Cosmic “evil one” and the human propensity to seek our own aggrandizement at the expense of everyone and everything else typically and periodically produce especially monstrous eruptions that leave the whole world reeling and the human race lying in a shambles. Shifting the blame, we point the finger at God as if the Deity is responsible for allowing us to behave demonically rather than exercising His omnipotence to prevent such horrors. The Accuser laughs all the while from behind the Oz-Curtain, and we fool ourselves that we are justified because God doesn’t just cut evil out of our hearts and kill the most monstrous perpetrators.
