In what way is "the strong delusion", yet weak?
It isn't.
The Antichrist will have a False Prophet who will work amazing miracles (2 Thessalonians 2:9b) by which people will be deceived (Revelation 13:12-14, Revelation 19:20, cf. Matthew 24:24). And God will send strong delusion on unrepentant people so that they will believe "the" lie (2 Thessalonians 2:11-12; in the original Greek, there is a "the" before "lie"), which could be the antichrist lie which has been around since the 1st century AD (2 John 1:7; 1 John 4:3; 2 Thessalonians 2:7a), and which in our future will deceive the world into consciously and openly worshipping both Lucifer (Satan) the dragon and the Antichrist (the individual-man aspect of Revelation's "beast") (Revelation 13:4-18, Revelation 12:9), the man of sin (2 Thessalonians 2:3-9), as God (2 Thessalonians 2:4, Daniel 11:36). The antichrist lie denies that Jesus is the Christ (1 John 2:22), denies that Jesus is the human/divine Son of God (1 John 2:22b), and denies that Christ is in the flesh (2 John 1:7), which denial is one of the key doctrines of Gnosticism.
But Christians need to be aware that during the Antichrist's future, literal 3.5-year worldwide reign (Revelation 13:4-18), even though the world will consciously and openly worship Lucifer (the dragon, Satan) and the Antichrist (the individual-man aspect of the beast) (Revelation 13:4-8, Revelation 12:9), this won't require that the Antichrist's one-world religion will say that Jesus is evil, or will turn the world against Jesus. For almost the entire world reveres Jesus, at least as being a good man. The Antichrist could confirm this basic world belief, but simply (in his words) "clarify" that while Jesus is indeed a good man, he isn't the Christ or the Son of God (1 John 2:22). No doubt the Antichrist will also deny that Jesus died on the Cross for our sins, as this, just as believing that he is the Christ and the Son of God (John 20:31, John 3:36), is one of the core beliefs of the gospel by which people become saved (1 Corinthians 15:1-4).
So what the Antichrist could do is keep the idea of a good Jesus, but strip it of everything by which Jesus saves people from hell. And this wouldn't require that the Antichrist deny Jesus' 2nd coming. Indeed, the Antichrist and his False Prophet (Revelation 19:20) could even try to employ to their own ends the Biblical prophecy of Jesus' 2nd coming, as well as the Muslim prophecy which says that the miracle-working prophet Jesus will return bodily from heaven in the last days to bring the whole earth into the worship of the true God. For the False Prophet could claim that he is Jesus returned. And he could perform amazing miracles (Revelation 13:13) as purported proof of his claim (cf. John 3:2). This is one reason why it is important to know when and how the real Jesus' 2nd coming will happen (Matthew 24:29-31; 2 Thessalonians 2:1-8; 1 Thessalonians 4:14-17, Revelation 19:7 to 20:6, Zechariah 14:3-21).
Once the False Prophet by his amazing miracles has brought the world under his spell (Revelation 13:13-18, Revelation 19:20), including many Muslims and Christians who may not care much for scriptural dogma, but could go wild over his signs and wonders, he could begin to (in his words)
"restore to the world the real message which was spoken by me (Jesus) at my first coming, and by the great prophet Mohammed, but which message became corrupted by power-hungry men when they copied and changed the early manuscripts of the Bible and the Koran". He could then gradually initiate the world into the Antichrist's Gnostic Luciferianism (1 John 4:3, Revelation 13:4-6), a religion which could have existed since ancient times in some "mystery" cults, and which still exists today in the highest degree of initiation of a worldwide secret society. The False Prophet could present his miraculously calling fire down from heaven (Revelation 13:13) as purported proof that Lucifer (the dragon, Satan) and the Antichrist are the true God (Revelation 13:4-8, Revelation 12:9), in an inversion of how back in Old Testament times, Elijah miraculously called fire down from heaven to prove that YHWH is the true God (1 Kings 18:37-39).
The person whom the Antichrist will revile is YHWH (Revelation 13:6, Daniel 11:36), whom many people mistakenly think of as being (in their words)
"the God of only the Old Testament, that cruel and hateful God who commanded people to commit genocide and kill babies (1 Samuel 15:3), whereas Jesus came and preached love for everyone (Matthew 5:44)". The truth is that Jesus confirmed that the God of the Old Testament, YHWH (Deuteronomy 6:4-5, Leviticus 19:18), is the same as the God of the New Testament (Mark 12:29-31), and that the Old Testament is true (Matthew 5:17-18, Luke 24:44-48). Jesus died for our sins in fulfillment of Old Testament prophecy from YHWH (Isaiah 53; 1 Peter 2:24). And he rose from the dead in fulfillment of Old Testament prophecy from YHWH (e.g. Psalms 16:10, Acts 2:31). Jesus died to establish the New Covenant (Matthew 26:28), which YHWH had foretold in the Old Testament (Jeremiah 31:31-34). And Jesus died to bring about the defeat of Satan (Hebrews 2:14), which YHWH had foretold from even the first book of the Old Testament (Genesis 3:15).
Nonetheless, building on many people's misconceptions of YHWH as being (in their words)
"the cruel God of the Old Testament", no doubt one of the Antichrist's chief blasphemies against YHWH (Revelation 13:6, Daniel 11:36) will be that YHWH is an evil god. This is one of the ancient blasphemies of Gnosticism, another being the antichrist lie that Christ isn't in the flesh (2 John 1:7). The world will be deceived into completely rejecting YHWH, and worshipping Satan and the Antichrist instead (Revelation 13:4-8, Revelation 12:9). Satan may be worshipped not as "Satan", which most everyone sees as a bad name (it means "Adversary"), but as "Lucifer" (Isaiah 14:12), which means "the morning star". The Antichrist could falsely say that it is YHWH who is the true "Satan", the true "Adversary" of mankind.
Because the Antichrist and his False Prophet (possibly masquerading as Jesus) will deny that Jesus is the Christ (1 John 2:22), and will deny that Christ is in the flesh (1 John 4:3), and because they will bring the world into the worship of Lucifer (the dragon, Satan) instead (Revelation 13:4, Revelation 12:9), they could falsely say that (the non-mortal flesh) Lucifer is the Christ, that the new name of Christ (Revelation 3:12c) is "Lucifer Christ". For just as "Lucifer" means "the morning star", so Christ is the morning star (Revelation 22:16b). Also, Christ identified himself with the serpent (John 3:14), and Lucifer is the serpent (Revelation 12:9). Also, Christ said "Ye are gods" (John 10:34), and it was the serpent who said "ye shall be as gods" (Genesis 3:5).
But the truth is that Lucifer fell from his office of morning star (Isaiah 14:12) and became Satan (cf. Luke 10:18). Jesus Christ has taken over the office of morning star (Revelation 22:16). And Jesus Christ identified himself with only the brass serpent on the pole in Numbers 21:8-9 (John 3:14), which typified Jesus Christ's crucifixion for our sins (John 19:16, Matthew 26:28). And in John 10:34, Jesus Christ (John 20:31) was quoting YHWH in Psalms 82:6-7, which shows that even though humans have knowledge of good and evil as gods do (Genesis 3:22), they will still die like humans (Psalms 82:7), contradicting the serpent's lie (Genesis 3:4). Nonetheless, the Antichrist could falsely say that Lucifer is the Christ and the true and beneficent God of mankind, and that the False Prophet is the miracle-working prophet Jesus (cf. John 3:2, Acts 3:22-24), returned to point the world to the true Christ/God. The Antichrist could falsely say he (the Antichrist) is the human/divine "Son" of Lucifer, who must be worshipped as God along with Lucifer (Revelation 13:4,8). This would be similar to how Biblical Christians rightly worship the human/divine Jesus Christ (John 1:1,14) as YHWH God (the Son) along with YHWH God the Father (John 20:28, Hebrews 1:8).
Near the end of the future tribulation of Revelation chapters 6 to 18 and Matthew 24, unclean spirits like frogs will come out of the mouths of Lucifer, the Antichrist, and the False Prophet (Revelation 16:13). And these unclean spirits like frogs will go forth and perform amazing miracles to convince the world's armies to gather together at Armageddon (Har Megiddo: Mount Megiddo in northern Israel) (Revelation 16:16) in an attempt to fight and defeat YHWH himself (Revelation 16:14, Revelation 19:19). After gathering together at Armageddon, the armies will travel south and pillage Jerusalem, right before the real Jesus (who is YHWH: John 10:30) returns from heaven and defeats them completely (Zechariah 14:2-21, Revelation 19:20 to 20:3).
