4But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication.
15So hast thou also them that hold the doctrine of the Nicolaitans, which thing I hate.
16Repent; or else I will come unto thee quickly, and will fight against them with the sword of my mouth.
Any philosophy of doctrine that suggest that you can commit fornication and still be saved is authored by the same demons that were teaching these lies in the churches of Asia. Jesus warned all churches of all times because he knew that this is the root of all false teaching we would contend with. Jesus is Lord of all or he is not Lord at all. Reject false teaching that suggests you may wallow in your sins of the flesh and still be saved.
