The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, and with all unrighteous deception
(2 Thessalonians 2:9-10)
For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; and they will turn their ears away from the truth, and be turned aside to fables.
(2 Timothy 4:3-4)
Understand that by failing to warn about the mark's penalty, more and more pastors are becoming Satan's advocate. The door to hell is opened by so-called men of God who give false assurance to unsuspecting congregations, but how does this happen? The Bible prophesies of the great apostasy we presently see in churches today. These doctrinal errors and perversions will grow much worse. They are signs of the end.

As more pastors are becoming wicked and removing God's penalty for the mark of the beast, wisdom and the knowledge of eschatology becomes more paramount. Christians have woefully dismissed eschatology and the rapture as non-salvation matters, but in these last days every believer must align themselves to the truth of God's Holy Word.
Take heed that no one deceives you. For many will come in My name, saying, ‘I am the Christ,’ and will deceive many.
(Matthew 24:4-5)
Then many false prophets will rise up and deceive many.
(Matthew 24:11)
For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect.
(Matthew 24:24)
For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted—you may well put up with it!
(2 Corinthians 11:4)
