Paul comforts his brothers by saying to them that those who have died in Christ, would rise at his coming.., and we should not grieve so like those who have no hope.
For the lord shall descend( he will come the same way he left), the dead in christ are raised. (Note that living believers are not raptured beforehand, or before the lords coming again) but we will be changed and will rapture with them,in the twinkling of an eye, to the lord 4 ever...
Peter sees the last judgement clearly, in 2pet3, also tied in with the second coming.
They looked to a New heaven and earth- REV 20-21.
They looked to the day of his coming in which the heavens dissappear and the earth melts-The great white throne.
Paul also sees this in 2thess 1.
