Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, 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. (Jhn. 5:28-29)
What could have been the reason for the Jews' marveling? Did they believe there would be separate resurrections for the righteous & wicked?
For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep .For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first: (1 Thess. 4:16)
Paul must have known what Jesus had said, but yet he holds on to the belief of separate resurrections.
