I will get the last laugh....brother. You are very clearly in the wrong here. VERY clearly.
No, you read it again. I guarantee you have me cracking up harder than you are because you are clearly not reading it carefully at all.
1 Corinthians 15:20 But now is Christ risen from the dead, and become the firstfruits of them that slept. 21 For since by man came death, by man came also the resurrection of the dead. 22 For as in Adam all die, even so in Christ shall all be made alive. 23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
This ABSOLUTELY does NOT say that those who are His at His coming are the first resurrection. That is ludicrous. Paul said there's an order to the resurrections. There is no order to the resurrections in your false interpretation of the passage. The order is Christ's first. Period! Paul did not say "Christ the firstfruits AND they that are Christ's at is coming", he said "Christ the firstfruits; AFTERWARD they that are Christ's at his coming". So, if you took your premil glasses off that are blinding you, you could clearly see that when Paul said "every man in his own ORDER, the ORDER was Christ's resurrection first. Next in ORDER (AFTERWARD) are "they that are Christ's at his coming". So, you are clearly trying to make this passage say what you want it to say instead of accepting what it actually says.
Acts 26:23 That Christ should suffer, and that he should be the first that should rise from the dead, and should shew light unto the people, and to the Gentiles.
This was Paul speaking and, once again, we can see that he taught that Christ's resurrection itself was the first resurrection!
