We are truly saved only when we are delivered from death, pain, sickness, sin and the Devil. Until the "new heavens and the new earth" (Rev 21) are created and I am in it partaking of the Water of Life (Rev 22), then i am saved.
That's what it is to be "delivered", salvation means "deliverance" in Greek.
Why crown yourself as victor when you are still struggling in the arena? Does an athlete claim victory before he defeats all his enemies? The last enemy is death (1 Corinthians 15:26)
