Okay, that's fine, but it doesn't quite answer the question that was posed in the topic of the thread.
Here was the question: What precisely do you mean by the saving of one's soul?
The answer is simple, in a way: Saving one's soul is saving one's life for and in the future - i.e., at the resurrection, which is settled at the time of one's earthly death.
Now, naturally, the question pops up of "How does one save one's life/soul?" The answer to that is the Gospel of Christ. It is to accept and obey that Gospel, nothing else is all that important!
Now let's let the discussion continue :-)
OK
