What Is the Strong Delusion God Will Send in the Last Days?

Second Thessalonians 2:11-12 says, “And for this reason God will send them strong delusion, that they should believe the lie, that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.”

What is the strong delusion God will send in the last days, and why will He send it?

  • The strong delusion is related to the return of the demonic influences and principalities illustrated in Daniel 10 and referenced in Genesis 6.
  • It will be sent because people rejected the truth.

2 Thessalonians 2 | Paul’s Second Letter to the Church in Thessalonica

Paul’s letter to believers in Thessalonica hits a weak spot in their faith. They had grown spiritually, yet they still had faulty thinking about “the day of the Lord.”

He assures them that they haven’t entered the day of the Lord (or the Tribulation) but outlines some events that will take place before the day begins.

  1. A rebellion against God
  2. The man of lawlessness revealed


“Don’t be fooled by what they say. For that day will not come until there is a great rebellion against God and the man of lawlessness is revealed—the one who brings destruction.”—2 Thessalonians 2:3 (NLT, emphasis added)

Paul continues, “And now you know what is restraining, that he may be revealed in his own time. For the mystery of lawlessness is already at work; only He who now restrains will do so until He is taken out of the way (2 Thessalonians 2:6-7, emphasis added). 

The words “taken out of the way” refer to the rapture of the Church. The Holy Spirit within the Church is holding back evil from completely taking over humanity. But there will come a time when He (the Holy Spirit) is taken out of the way, and lawlessness will abound. 

Jesus said, “And because lawlessness will abound, the love of many will grow cold. But he who endures to the end shall be saved” (Matthew 24:12-13). Yes, it will get worse before it gets better, but we can trust God’s promise to save those who choose Jesus.

Paper with the word truth written across it and lie written on it once, with a magnifying glass over the word lie.


The Coming of the Lawless One, Unrighteous Deception, and the Strong Delusion

The Man of Lawlessness Does False Wonders

The lawless one is the Antichrist, the person whom Satan will energize to do false signs and wonders. Some of the false wonders include bringing fire from heaven to the earth in public view (Revelation 13:13) and giving an idol—the image of the beast—the power to speak (Revelation 13:15). The purpose of the false signs is to deceive people into thinking he is Christ the Messiah.

Those Perishing Believe the Unrighteous Deception

Satan is “the deceiver of the whole world” (Revelation 12:9). Paul reminds us in Thessalonians 2:10 that deception infiltrates the hearts and minds of those perishing. They are perishing because “they did not receive the love of the truth, that they might be saved.” Rejecting Jesus’ gift of salvation prohibits the Spirit from dwelling within a person, which allows the mind to be deceived (see 1 Corinthians 2:14).

God Sends Them a Strong Delusion Because They Reject Truth

“Those who reject the truth but had pleasure in unrighteousness” (2 Thessalonians 2:12) are not believers, and God sends them a strong delusion (see also Romans 1:28), sealing their fate based on their choice to receive a lie.

After the Rapture…

There will be a worldwide revival after the rapture of the Church for those who reject the Antichrist. But if the Church is removed, how will these people come to accept Christ and know the truth? Revelation 7 tells us that the revival begins with 144,000 Jews who will embrace Jesus as their Messiah and reject the mark of the beast.

The implication in 2 Thessalonians 2 is that the revival will not happen among those who heard the Gospel before the rapture. These people heard and rejected it and will be under the strong delusion—the biggest lie ever told.

What is the lie they will believe?

The Strong Delusion God Will Send

A study of biblical truth, history, archeology, and anthropology reveals that the strong delusion God will send is likely related to the return of the demonic influences and principalities illustrated in Daniel 10 and referenced in Genesis 6. 

Daniel 10 reveals there is intelligent life in outer space. Now, this intelligent life is not what you think. It isn’t alien life forms depicted in movies. Looking at the text, you find supernatural beings in the heavenly realm are intelligent life forms that fight against God’s angels. They are Satan’s angels.

Daniel 10 provides a glimpse of the warfare between the angels of God and the angels of Satan as they battle for God’s throne. The dominion of Satan and his army of fallen angels is in the heavenlies, which is outer space. 

The Heavenlies   

In the first spiritual war, Satan attempted to overthrow the throne of God in the third heaven. He was thrown out of the third heaven and now resides in the second heaven. 

The Apostle Paul said in 2 Corinthians 12 that he was caught up to the third heaven. The implication is that if there is a third heaven, there must be a first and a second heaven.

Psalm 148 breaks down the three heavens:

  • The third heaven is the dwelling place of God and His throne room. 
  • The second heaven is the sun, moon, and stars. In other words, outer space, the cosmos, or the heavenlies. 
  • The first heaven is the earth and its atmosphere.


Paul writes in Ephesians 6 that we do not war against flesh and blood but against powers and principalities in heavenly places. This war against powers and principalities in the heavenlies is because Satan and his angels reside in the second heaven.

The Strong Delusion Will Come from the Heavenlies

Daniel 10 mentions the prince of Persia and the prince of Greece. At this time in history, Satan was already preparing demonic principalities to rule over this area. 

Satan is called the prince and power of the air (Ephesians 2:2) because this is where (in the heavenlies) he plots his assault on the human race. 

Many think of Satan existing in hell, but this is not his location at this time. Jesus said hell was prepared for Satan and his angels. Eventually, they will be bound there, but they are not there yet. Currently, they are in heavenly places. 

Satan’s method against the human race has moved from heaven to the earth using temptation, deception, corruption, persecution, infiltration, and even cohabitation.

Summary: The Strong Delusion and the Days of Noah

The strong delusion God will send in the last days will be like the days of Noah. What did Jesus mean when he said, “But as the days of Noah were, so also will the coming of the Son of Man be” (Matthew 24:37)? What were the days of Noah like? The earth was invaded by heavenly beings from outer space masquerading as gods (see Genesis 6:1-4 and Jude 6-7). They were fallen angels

Biblical, historical, and archeological evidence demonstrates that at various times throughout human history, god-like beings have mingled with human civilization.
