Video from Desiring God
"Conspiracy theories — Christian or otherwise — are nothing new. But how can we talk to friends who find themselves gripped by them? Christian conspiracy theories. That’s today’s theme. We need to address them, as we hear from Lindsay, a listener with today’s question. “Hello, Pastor John, and thank you for this podcast. I have a friend who is convinced that the new COVID-19 vaccines are ‘the mark of the beast.’ Anyone injected is given over to Satan and is thereby lost forever, per Revelation. I’m very much unconvinced of this. But how would you respond to Christians who are given to these types of spiritual conspiracy theories? And then, if possible, what exactly is the mark of the beast in Revelation 16:2 and 19:20?” from video introduction.
Conspiracy Theories do not glorify God and do not serve the people around you. In our age they are no doubt more distraction and evil if nothing else. Don't waste your precious time on this earth with worldly things. Focus on Christ!
