For this reason God sends them a powerful delusion, leading them to believe what is false, (2 Thess. 2:11 NRS)
The powerful delusion is the deceiving energy (1753 ἐνέργεια energeia) of spiritism (2Th. 2:2, 7-11) deluding its victims falsehood (4106 πλάνη plane) is truth. God “sends” this powerful delusion when He stops restraining spiritism granting the rebels their preference for spiritism and its lies above the truth of God’s Holy Word and sanctification by God’s Holy Spirit (2 Th. 2:11-12. 1 Kings 22:21-23. Ezek. 14:9-11; Compare Jn. 17:17. 2Th. 2:13).
To illustrate the powerful delusion Paul describes he points to the deluding energy that was already working (2Th. 2:7) through demonic spirit prophecy and spurious letters (1Tim. 4:1. 1Jn. 4:1-6) that alarmed the Thessalonians the resurrection/gathering in the Day of Christ was already past, and they were left behind (2Th. 2:1-2, 7. 2Tim. 2:18).
Spiritism works inwardly inciting rebellion against God, working like a “secret power” or “mystery of lawlessness”:
a deluding influence so that they will believe what is false. NET
a power that deludes people so that they believe what is false, NJB
an inworking of error, to the end they should believe in the falsehood ROT
an influence that will mislead them so that they will believe the lie. CEB
The “mystery of lawlessness” is the polar opposite of the “mystery of godliness” (1Tim. 3:15 versus 1 Tim. 4:1; Compare 2Th. 2:9-12 versus 2Th. 2:13-15).
Ye know that ye were Gentiles, carried away (520 ἀπάγω apago) unto these dumb idols, even as ye were led (71 ἄγω ago) (1 Cor. 12:2) KJV
While speaking about spiritual gifts Paul warns the Corinthians to recall their experience of the deluding influence of spiritism when against all rational thought they went to dumb idols to hear what they had to say (cp. dumb idols speak (1Tm. 4:1. 1Jn. 4:1; Lk. 8:2. 2Cor. 4:4). Telepathic suggestion then led (71 ἄγω ago: like animals to the slaughter) “by the nose” wherever the demons wanted them to go (1Cor. 12:1-2).
Satanic “energy inworking error” employs telepathic suggestion and “experiences” to supplant critical thinking.
These hear the gospel but on their way home the Devil telepathically argues against it preventing belief:
“Those by the wayside are the ones who hear; then the devil comes and takes away the word out of their hearts, lest they should believe and be saved. (Lk. 8:12 NKJ)
3 But even if our gospel is veiled, it is veiled to those who are perishing,
4 whose minds the god of this age has blinded, who do not believe, lest the light of the gospel of the glory of Christ, who is the image of God, should shine on them. (2 Cor. 4:3-4 NKJ)
The deluding energy of spiritism inspires heresy and false prophecy:
Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons, (1 Tim. 4:1 NKJ)
1 Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world.
2 By this you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God,
3 and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world. (1 Jn. 4:1-3 NKJ)
The deluding energy of spiritism can disguise itself so well some believe its God who is tempting them:
13 Let no one say when he is tempted, “I am tempted by God”; for God cannot be tempted by evil, nor does He Himself tempt anyone.
14 But each one is tempted when he is drawn away by his own desires and enticed.
15 Then, when desire has conceived, it gives birth to sin; and sin, when it is full-grown, brings forth death. (Jas. 1:13-15 NKJ)
The deluding energy of spiritism has worked deception in everyone living, at one time or another:
1 And you He made alive, who were dead in trespasses and sins,
2 in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience,
3 among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others. (Eph. 2:1-3 NKJ)
Paul contrasts the damned deceived by the powerful delusion who don’t love the truth of God (2Th. 2:9-12) to the saved sanctified by the Holy Spirit believers in God’s truth (2Th. 2:13-16). When he did this, it painted a similar picture of the end time church Christ Himself painted:
24 Another parable He put forth to them, saying: “The kingdom of heaven is like a man who sowed good seed in his field;
25 “but while men slept, his enemy came and sowed tares among the wheat and went his way.
26 “But when the grain had sprouted and produced a crop, then the tares also appeared.
27 “So the servants of the owner came and said to him,`Sir, did you not sow good seed in your field? How then does it have tares?’
28 “He said to them,`An enemy has done this.’ The servants said to him,`Do you want us then to go and gather them up?’
29 “But he said,`No, lest while you gather up the tares you also uproot the wheat with them.
30 `Let both grow together until the harvest, and at the time of harvest I will say to the reapers, “First gather together the tares and bind them in bundles to burn them, but gather the wheat into my barn.”‘” (Matt. 13:24-30 NKJ)
18 Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come, by which we know that it is the last hour.
19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that they might be made manifest, that none of them were of us. (1 Jn. 2:18-19 NKJ)
Just as magician spiritism deluded Pharaoh he could defeat God (Ex. 7:11-13, 22), and God permitted it occur to punish Pharaoh the full measure of his sin, so also God lifts His restraint on spiritism the reprobates desire, lest any of them escape the full measure of punishment they deserve. Their covenant with Death (Is.28:15-18) served God’s purpose, that His judgments be manifest in them (Rev. 15:4 compare Ex. 9:16; Rom. 9:22)
Forensic analysis of scripture uncovers the end time falsehood. The paradox of opposing yet exalting above all called God is the big clue.
Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. (2 Thess. 2:4 KJV)
Its impossible to oppose ALL called God and then claim to be God. We must deduce the missing premise as scripture is always 100% correct and never in self-contradiction.
In “scientific atheism” there is no god, all appearing in human history are said to be extraterrestrial beings or myth. That is how the Antichrist opposes the historic definition of God (Dan. 7:25). It is claimed the Antichrist is a hybrid both “elohim” and “human”. The Antichrist will claim to be superior to all other Designer hybrids in history, and therefore higher in nature than even the “elohim Designers” themselves. Thus he exalts himself above all called God and claims to alone be God.
36 And the king shall do according to his will; and he shall exalt himself, and magnify himself above every god, and shall speak marvellous things against the God of gods, and shall prosper till the indignation be accomplished: for that that is determined shall be done.
37 Neither shall he regard the God of his fathers, nor the desire of women, nor regard any god: for he shall magnify himself above all. (Dan. 11:36-37 KJV)
So the Antichrist claims to be the Christ, but in such a way that denies everything Christians believe about God the only begotten Son and His Father, including the incarnation (1Jn. 2:22-23; 4:3. 2Jn. 1:7).
