“But how does he KNOW there won’t be a rapture?”
He doesn’t. Just who does he think will man the armies of good at the battle of Armageddon?? :)
I don’t when it will happen but the “rapture” will occur.
Those that deny it, well, they’ll be in for a big surprise and it certainly won’t be a secret!
Read 2 Peter 3 alongside of 1 Corinthians 3
The "Rapture" (and all forms of "Premillennialism") is destroyed by these Scriptures. Christ speaks of a 'final day'. He speaks of a single general judgment and resurrection. Acts tells us that the heavens must receive him until the restitution of ALL things. That's the New Heavens and the New Earth. The risen Christ is now "The Temple"; Christians are "the Temple of the Holy Spirit".
