Revelation has not told us much more than that. The teaching Church has given us only a few more ideas. Hell and heaven in the New Testament, unfortunately, are usually described in images of apocalyptic Judaism. It has been said that we do not like to think of our death any more than of our birth. Yet it is spiritually healthy to prepare for death.
Most people are very afraid of death.
St. Paul and the earliest Christians were anxious for death so they could be with Christ. But few of us today have such faith. Yet from faith there are many reasons to approach death with courage, confidence, and hope. It is appointed for people to die once, and after that comes judgment. The Church teaches that immediately after death some kind of judgment takes place, since the soul goes either to purgatory or heaven or hell.
