For the Gospel of Jesus Christ to become complete ... full, whole ... it must include two main parts: the Earth side and the Heaven side. 

First of all, we are spirit with a mind (part of our soul) living in a body which we call our "earth suit".  This allows us to function in both the physical and the spiritual realms.  We live here in the tangible, physical realm now, and in the future we'll live in the spiritual realm. 

God needs and wants to be the Major Player in our lives in both realms and this means that  we need to have a life in Christ which benefits us here and now as well as one which will benefit us later in the other realm.
