How in the world can you call death "...the first death?"
Spirit never dies. Bodies die all the time and they never
come back to life and never will, and nothing will ever change that.
If you follow the teachings of Jesus, "....the kingdom of God is
inside of you" - you will learn that you are an eternal spirit and
not just a temporal body. However, you don't discover this by reading a
book, no book - because you are the book. All questions about you and the
universe around you are inside of you, just as Jesus taught. By searching
where Jesus told us that the kingdom is located, you will discover yourself as
spirit, by experience, not by learning from a book.
Ecclesiastes 12:7 ......Then shall the dust return to
the earth as it was: and the spirit shall return unto God who gave it.
