He might want to re-read Revelations.
Revelation 13:16-18 King James Version (KJV)
16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.
18 Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.
Revelation 14:9-12 King James Version (KJV)
9 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,
10 The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
11 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
12 Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
I don’t think his cult encourages that.
If you read Rev 13:9-10, we see the people that are left behind cannot even shoot anyone or steal food after the Rapture or they won't be considered "Christian" and their names will not be in the "Book of Life". Attention all preppers.
If you weren't following the Commandments of God at the time of the Rapture, you get left behind as a foolish "virgin". Then there will be no more grace given to go to heaven, but you must literally die to get there. That is the saints mentioned under the altar crying out for vengeance. The vengeance won't come until the last holdout is killed. Salvation is different than Rapture. You can be saved, but not go in the Rapture. Read the letters to the churches in Rev 2-3. The letter to Philadelphia says they will be spared the trial coming to the whole earth. The rest of them pretty much say God knows their works, but hey have some area God wants them to work on. The church at Sardis is the dead church and is singled out that Jesus will come as a thief and they won't be watching for Him to come. They will even have their name blotted out of the Book of Life. The church at Smyrna is the persecuted church and He just tells them to "Fear Not". They will be killed for Christ and get their white garment for that. He is basically saying you can either live for Me, or die for Me and be rewarded. It's better to live for Him now, than spend your Sunday in a Lazy Boy watching the boob tube thinking everything has been taken care of when you were 18 years old. You MUST be found, "so doing" when Jesus comes for His Bride, or you won't come. Since we are no longer under the Law, He gave us a new commandment in the New Covenant. Love the Lord with all your heart, soul, mind, and strength, and love you neighbor as yourself and you will be in the church of Philadelphia. The Bride is the Christians that died under water and rose as a new creature by the Holy Spirit. If you just got wet, that's not being "born again". The thief on the cross believed God, but was not baptized, so he died in Christ and went to heaven. If you want to be Raptured, then that involves water baptism and producing Spiritual fruit for Jesus Christ.
If I could talk to you for 5 minutes and not know that you are a born again Christian, you probably aren't going in the Rapture. If if it breaks your jaw to say "Thank you Jesus" or "God Bless You!", There might be a problem. If you don't read your Bible or go to church regularly, there might be a problem. If you are ashamed for anyone to know you are a Christian, well, you get the picture. If you haven't been "immersed" in water, you must go through the water baptism to die to the flesh and live in the Spirit. That's not sprinkling with a rose or getting wet as a baby. You must personally accept Christ. Mamma can't do it for you. Your denomination doesn't save you. If you are truly saved, there should be fruit and that entails more than just staying out of jail. It's all there word for word in scripture.
Oh, and one last thing,....Rev 1:3 says that you will receive a blessing for reading Revelation. The blessing is that the book makes plain how to avoid being left behind. Matt 24 is a mixture of verses about the Rapture and the Second coming. You have to discern which is which. Verse 3 also makes it plain that Revelation is a prophesy. That means it didn't happen in 70 AD as some believe. John was in exile until at least ~84-90 some odd before he was released to Ephesus where he died. It's a prophesy, not historical.
