Thing is, considering the Church is the temple of God....I don't see how the anti-Christ will sit in the christians who are the temple.
1 John 2:18 Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time. 19 They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us. 20 But ye have an unction from the Holy One, and ye know all things. 21 I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth.
If saved believers believe the lie that they can receive the Holy Spirit by a sign, then they are opening themselves up to suffer a thief to break through as God will permit that strong delusion to occur for believing that lie.
2 Corinthians 11:1Would to God ye could bear with me a little in my folly: and indeed bear with me. 2 For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ. 3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. 4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
2 Corinthians 13:5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
1 Timothy 4:1Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; 2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;
2 Thessalonians 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, 2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand. 3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first.....
7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
9 Even him, whose coming is after the working of Satan with all power and signs and lying wonders, 10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11 And for this cause God shall send them strong delusion, that they should believe a lie: 12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because
God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth: 14 Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ.
15 Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
This was happening even in Paul's days as he addressed those that become disorderly ...... like we have seen in the holy laughter movement and being drunk in the spirit, and slain in the spirit, and so forth where confusion reigns which God is not the author of.
2 Thessalonians 3:1 Finally, brethren, pray for us, that the word of the Lord may have free course, and be glorified, even as it is with you: 2 And that we may be delivered from unreasonable and wicked men: for all men have not faith. 3 But the Lord is faithful, who shall stablish you, and keep you from evil. 4 And we have confidence in the Lord touching you, that ye both do and will do the things which we command you. 5 And the Lord direct your hearts into the love of God, and into the patient waiting for Christ. 6 Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he received of us. 7 For yourselves know how ye ought to follow us: for we behaved not ourselves disorderly among you;
14 And if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed. 15 Yet count him not as an enemy, but admonish him as a brother.
So those that have gone astray are at risk of being left behind and thus damned as vessels unto dishonor in his House unless they repent before the Bridegroom comes.
Matthew 12:38-40 & Revelation 2:18-25
This is how I see the spirit of the antichrist being in Christians using tongues for private use to prevent them from praying normally.
1 Corinthians 12:7-14,19-21;1 John 4:1-6
This is why tongues are not for private use and it is just gibberish nonsense because it is not of Him for why it is not coming with interpretation, and thus of the world's pagan supernatural tongue as they speak as the world speaks by that spirit of the antichrist.
Anyway, just sharing how there are other antichrists and how the spirit of the antichrists can be in believers that err.
