"Now at that time Michael, the great prince who stands guard over the sons of your people, will arise. And there will be a time of distress such as never occurred since there was a nation until that time; [Matthew 24:21, Mark 13:19] and at that time your people, everyone who is found written in the book [Luke 10:20], will be rescued [Matthew 10:22, Matthew 24:13]. Daniel 12:1 (NASB)
Who were "Daniel's people", JLB??? To whom was the promise of a resurrection made???
The resurrection is clearly set in the time frame of the "great tribulation" of Jerusalem, so this promise of a resurrection you see as being universal and future was neither. It was as unique an event as the final destruction of the Old Covenant kingdom itself!
You can't take Daniel 12:2 apart from Daniel 12:1 and verse 1 alone refutes your position!
