All His prophesies have been fulfilled. This one will be fulfilled also. The life of the age to come is life in glory and joy, in the kingdom of the Creator, in the embrace of the Father, in Paradise. It is life unswayed by fear, untroubled by worry, unmarred by sickness, immune to decay and death. All the troubles of life on earth will seem like a drop of salt water in a fresh water river when compared to life in Paradise.
Earthly life is to that life what the shadow of a tree is to a tree.
The shadow resembles the tree, but is not the tree. Likewise, the earthly life of man resembles life, but is not true life. It is like sleep compared to consciousness. When we enter into that life, it will be like awakening from sleep and entering into consciousness, into the kingdom of consciousness. This kingdom of consciousness is the immortal kingdom of God.
