Yes, all. That's what Jesus said. Do you trust in what Jesus taught or not?
John 5:28 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, 29 And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
He said the hour is coming when ALL that are in the graves will be resurrected. It couldn't be more clear. Yet, you believe multiple hours are coming when the dead will be resurrected. That's not what Jesus taught.
All?
That would mean that there will be no more bodies left to die at that point in history.
The end of history on earth as we know it...
