What will it take?
Or is it just not in our nature?
I am NOT talking here, in this forum, but rather the world, all religions all nations, al people.
But we do need to start here ...if we expect it to happen elsewhere
Personally I see all things are made new and as such our nature is now inclined to embracing our oneness.
The question you ask has been answered by the Message of Baha'u'llah and is being implemented throughout the entire planet in all Nations. The process started in AD1844, or AH1260.
"The earth is but one country and mankind its citizens."
"Let not a man glory in this, that he loves his country; let him rather glory in this, that he loves his kind"
Peace will only possible when the world eventually submits to what that Message contains and in these early years, that does not mean that many will identify as being Baha'i, but it does mean that many will embrace the principals needed to embrace unity as one people on one planet.
Baha'u'llah has made it very clear that all Faith is from the One God. The realisation that we are one people under one God is the Elixer.
Every problem has been offered a solution. We have been told what our disunity will reap upon humanuty as a whole. The following words of Bahá’u’lláh are indeed significant as we pause to reflect upon the present state of a strangely disordered world:
“How long will humanity persist in its waywardness? How long will injustice continue? How long is chaos and confusion to reign amongst men? How long will discord agitate the face of society? The winds of despair are, alas, blowing from every direction, and the strife that divides and afflicts the human race is daily increasing. The signs of impending convulsions and chaos can now be discerned, inasmuch as the prevailing order appears to be lamentably defective.”
What a great day we live in!
