No, saying the Remnant would be some of the Church is without any evidence in the text whatsoever.
If you believe on Jesus Christ unto your Salvation, then I would not like you to have to go through the awakening shock of seeing our Lord Jesus coming when you had wrongly thought He was already here with the disguised "another Jesus" that's to come first.
That's part of Paul's warning Message in 2 Corinthians 11 about the "another Jesus". It's also his warning in 2 Thess.2 about the one coming to sit in the temple of God, and exalting himself over all that is 'called' God, or that is worshipped.
There are five foolish virgins that somewhat prepare to go meet the Bridegroom at the midnight hour (Matt.25). They won't be 'spiritual' virgins when Jesus returns to find they allowed themselves to be deceived into bowing to the false messiah that comes first. That's about the 'pseudo Christ' which our Lord Jesus also warned us about in Matthew 24:23-26, and with the "abomination of desolation" prophecy from the Book of Daniel. It's also the "another beast" He warned us about in Revelation 13:11-17.
Per Matt.25, the five foolish virgins go to 'buy' Oil, but can they really? NO! No can buy that Oil which represents The Holy Spirit. Simon the sorcerer in Acts 8 offerred money to buy The Holy Spirit, remember?
But that's what many in the Churches are being taught today, it's what some Churches on the Prosperity Ministry doctrines are all about! Little old ladies sitting in front of their TV sets writing checks to some fancy dressed professional mouth-piece asking for money, preaching about money, thinking about money, because those preachers are after... money. Our Lord Jesus called those a "hireling" in John 10; when the wolves come in those run, and don't care about His sheep.
Same kind of thing goes for ANYTHING pushed in Christ's Church that does not involve building the believer up in His Word of understanding so as to not be deceived by what's coming. How many Churches are actually preparing their congregations for the coming false messiah? Very few. What are those Churches doing instead?
1. They're instead teaching to 'fly away' to the first supernatural messiah that shows up, which will be the "another Jesus", the 'pseudo Christ', the "man of sin", "that Wicked", the "dragon", "that old serpent", the Devil. (See Ezekiel 13 about this).
2. Or they're preaching prosperity, materialism, world peace, internationalism, a joining with other religions of the world, Christ's Kingdom of the now, without Jesus' coming, etc.
3. Or they're preaching beautiful, sweet, loving messages that really 'sound' great to the ears, that make you feel real good for a day, but do nothing to prepare you to make a 'stand' for our Lord Jesus in the "evil day" of the coming "great tribulation", when false messiah will appear and command all to bow in worship to him.
4. Or they're preaching reliance upon another 'spirit' they claim is The Holy Spirit, which tells them they don't need to study God's Holy Writ, essentially that they've become their 'own' Christ, as if they have become 'gods' to themselves, which allows them to re-write God's Word anew (they think).
All we have to do is wait for our Lord Jesus' second coming to end the "great tribulation" and destroy that wicked one with the brightness of His coming, like Apostle Paul said in 2 Thess.2.
Zeph 3:8
8 Therefore wait ye upon Me, saith the LORD, until the day that I rise up to the prey: for My determination is to gather the nations, that I may assemble the kingdoms, to pour upon them Mine indignation, even all My fierce anger: for all the earth shall be devoured with the fire of My jealousy.
(KJV)
Why will The LORD be jealous in order to do that? What's going to occur on this earth just prior to Christ's coming that's going to make Him jealous? See Ezekiel 8. Some in His Church falling to bow in false worship to a false god, an idol even, is an abomination to Him, and the image of the beast false worship coming is going to make Him jealous! Jealous for whom? for Satan's servants? NO! For His people that allow themselves to be deceived by His enemies into bowing to the coming false messiah and that beast image of Rev.13, thinking that false one is Him! Our LORD said... WAIT for Him!
