The Greatest Deception of the 21st Century
In short: BOOM!
I wish you would bear with me in a little foolishness. Do bear with me! For I feel a divine jealousy for you, since I betrothed you to one husband, to present you as a pure virgin to Christ. But I am afraid that as the serpent deceived Eve by his cunning, your thoughts will be led astray from a sincere and pure devotion to Christ. For if someone comes and proclaims another Jesus than the one we proclaimed, or if you receive a different spirit from the one you received, or if you accept a different gospel from the one you accepted, you put up with it readily enough.
2 Corinthians 11:1-4, ESV
But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed.
