For the Gospel of Jesus Christ to be complete ... full, whole ... it must include two main parts: the Earth side and the Heaven side. The Apostle Paul said that if we only have hope in Christ after we die, we are to be pitied more than all men.
First of all, we are spirit, with a mind (which is part of our soul), living in a body ... our earth suit ... which allows us to function in both the physical and spiritual realms.
We live here in the tangible, physical realm now ... in the future we'll live in the spiritual realm. God needs and wants to be the major Player in our lives in both of these realms, meaning that we need to have a life in Christ which benefits us here and now, as well as one which benefits us later in Heaven.
Our new life in Christ requires us to have a new birth, and this new life results in a new identity.
If you have received the new birth, having been born again simply by asking Jesus to be your Savior and Lord, you are, right now, spiritually alive in Him.
You will never be more spiritually alive than you right now. Your spiritual life in Christ began when you personally trusted Him to be your Savior, and will continue on when you physically die.
Salvation is not a future addition ... it's a present transformation that occurs at your spiritual birth not your physical death.
