The apostle Peter indicated that many would come in the name of Christ, yet deny Him as both Lord and Savior. The apostle also said that these same apostates would make merchandise of the members of the churches. In other words, like the Nicolatians, they would use the money to gain advantage, (Rev. 2).
The Scripture warns us to be careful about companionship with the people of the world. In (2 Jn.7), “For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an Antichrist.” And then in (2 Jn. 9), we see a separation is to be established between the believer and unbeliever. “Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.”
We are seeing people fall away from Christ left and right. They are in church one night and the next night back into world. It is terrifying to see a Christian backslide because they usually become spiritual monsters. One pastor fell away from the pulpit several years ago, today he sits on a bar stool drinking. When the bar closes each night,this Pastor takes people to his house continuing to drink, then they watch his old sermons and laugh and mock Jesus together! He became an evangelist for Satan!
