All the kingdoms of God and the universe always exist, man will go into space and evolve, but the spiritual path proper leads to the spiritual kingdoms, that are not of this world. Iow, a spiritual aspirant doesn't have to wait until the future of science and faith working together arrives, now is all there ever is, and it is eternal.
The purpose of this life is indeed to find our spiritual selves as a material being.
This creation has been given to help man develop those capacities in an ever advancing state of being.
So Science and Faith have always been the wings that man can soar to greater heights upon, or uses them in a way that darkness prevails.
The purpose is for us to find and embrace the Light that is in us all, it is also reflected in thr material world, I see it is the power that drives creation a power we are told exists, a power Baha'u'llah prays we do not find until we are eady for it, but I wonder if we did with atomic energy with these quotes.
"Strange and astonishing things exist in the earth but they are hidden from the minds and the understanding of men. These things are capable of changing the whole atmosphere of the earth and their contamination would prove lethal. (Baha'u'llah)
Then in 1911 in Paris in a conversation with Viscount Arawaka, the Japanese Ambassador to Spain, 'Abdu'l-Bahá spoke these words:
"Scientific discoveries have increased material civilization. There is in existence a stupendous force, as yet, happily, undiscovered by man. Let us supplicate God, the Beloved, that this force be not discovered by science until spiritual civilization shall dominate the human mind. In the hands of men of lower material nature, this power would be able to destroy the whole earth.'"
So I see that power may be bigger than atomic, it may be atomic combined with some form of magnatisim.
