This topic is dear to my heart, as this is what I live for, a day when as a citizen of the World we all work together for the common good for all humanity.
This is not about your faith verse my faith, or faith verse atheists.
In the big picture I see faith teaches about the possibility and inevitability of a united humanity and I would assume many people of no faith long for a day when they an live in peace with equal opportunities in life.
Way back in the 1800's, just as the world was considering the smallness of our part in the universe it was said that peace would only come in one way, that path is to the extent we choose to submit to given laws, that will need to be establish by a world tribunal.
So this is the wisdom to be considered and debated, is this what we need, will it be what we need?
"... The time must come when the imperative necessity for the holding of a vast, an all-embracing assemblage of men will be universally realized. The rulers and kings of the earth must needs attend it, and, participating in its deliberations, must consider such ways and means as will lay the foundations of the world’s Great Peace amongst men. Such a peace demandeth that the Great Powers should resolve, for the sake of the tranquillity of the peoples of the earth, to be fully reconciled among themselves. Should any king take up arms against another, all should unitedly arise and prevent him. If this be done, the nations of the world will no longer require any armaments, except for the purpose of preserving the security of their realms and of maintaining internal order within their territories. This will ensure the peace and composure of every people, government and nation. We fain would hope that the kings and rulers of the earth, the mirrors of the gracious and almighty name of God, may attain unto this station, and shield mankind from the onslaught of tyranny."
In this debate, even though this is a teaching of my faith, remember it will not be the Baha'i that will do this, if it is to happen. So will it and does it need to happen?
