Question:

This may seem a silly question but I studied out 1Corinthians 15:50-54.
Paul says that our bodies, which are perishable and mortal, will be
transformed into heavenly bodies which are imperishable and immortal.
Would I be right in thinking that this means we will live infinitely when
we are saved?

Answer:

This is not a silly question. The obvious interpretation, and the common
interpretation of the passage is that “the perishable has been clothed
with the imperishable, and the mortal with immortality” implies those who
are saved will live forever; ie an infinite amount of time with God. The
Greek word used here is the word athanasia which means immortal or
immortality. What it means literally, I believe, is that we will no
longer be subject to death in the physical sense. Whether this means that
we will exist forever, I suppose, is debatable. All I can say is that
this is the obvious meaning, and you will have to wait to ask God himself
about the infinity idea. What I can say without a doubt is that the
passage in 1 Corinthians 15:50-54 is very encouraging. One thing for sure
is that what God has in store for those of us who are saved is infinitely
better than for those who are not saved. I believe that is all we need to
know.
