A lady visited our Saturday evening service intending to instruct our congregation that accepting COVID vaccinations amounts to receiving the 'mark of the beast.' She sincerely believes God called her to preach such a message. Sadly, though well-intentioned, the lady lacks spiritual stability and is "tossed to and fro, being carried about with every wind of doctrine, by the sleight of men." She is the victim of 'cunning craftiness.' "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places" (Ephesians 6:12). Unfortunately, many church-going Christians are in a similar position to this unfortunate woman.
