When you enter into another man’s house, you submit to the authority of that house. This is the Hebrew way of YHWH. Only a thief, who enters through the back door in secret would not.
As the owner of a local auto repair shop, we also sold batteries, tires and a few other parts in our storefront, that we bought from wholesalers. But the majority of the parts we bought were from the local auto parts store, where the public buys. So if I were standing in the auto parts store and another customer was buying a battery or something we also sold, I had to bite my lip not to tell the person, “I have a better deal than that.” Why? Because I would be as a snake in the grass to use another man’s house to further my own house, when I do it against the owner of the house. You don’t use another man’s resources against him. He paid money for his store, and extra for the location, and advertising. You want to walk in for free and steal from him? It doesn’t matter that your goal is to save someone else money. It’s still dishonest to steal from one to give to or save another.
If when you learn that you are in Babylon, you make the excuse that you need to stay in this church to help lead others out from under the false teaching, then you are the dishonest destroyer from within. It doesn’t matter that you are trying to save someone from the destructive lies. It would be dishonest to be in the house for the purpose of destroying it, because you are there under false pretences. You cannot lead anyone out when you yourself are not out. You are in another man’s house. Get out if you cannot submit to the authority of that house.
