Matthew 24:10-14, 24

And then many will be offended, will betray one another, and will hate one another. Then many false prophets will rise up and deceive many. And because lawlessness will abound, the love of many will grow cold. But he who endures to the end shall be saved. And this gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come.

For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect.
