Faith is the belief in things not seen. This is not only true in religion, but all secular innovation uses the same schema. This topic is saying if you come up with a new embryonic idea, that is not yet tangible, so others can see it, you need to forget about it.
Such a world will stop in its tracks, at a point on time. That point in time was built on the shoulders of past visionaries, but no new visionaries after that. This is common thinking for those who think now is the best of all times, and nothing new needs to be added, and all change need to be avoided, instead of embraced.
The faith of the believers, of all things not seen, both religious and secular, is the living spirit in the otherwise sterile world of temporal perfection. The resistant to the unseen future, is often less about maintaining temporal perfection and more about power and keeping the seat at the big table. If the horseless carriage was to success what becomes of the horse and buggy and all those who now live large?
The faithful in religion, sense the future that forms via the spirit; thought and imagination. It appears in material reality for all to see only after it can be transposed into material form. They set an example of faith, for others to see and follow, even if they are not religious. The living future, has many paths.
The religious and all faithful, they have a connection to time; future and timelessness, that give some the feelings God. People of all kinds and walks of life, get this extra feeling to compensate for the struggle, this gift of seeing, can create. This gift and the feeling of timelessness makes it hard to shake their faith.
