I understand that you believe that Bahaiullah is the person who has this force. But isn't the one who would do this, do this in his lifetime? After all if personal power from a transcendent source is the thing that is lacking to get to world peace, the person with such power has to be alive to move nations. Otherwise all you have is what everybody else has, inspirational books and statements from deceased founders. And if you suggest that the difference is recency, one could point to renewals and modernization with ancient traditions brought about by persons of great inner power. Examples like Gandhi, Vivekanada (Hinduism), Dalai Lama, Thich Nath Hahn (Buddhism), Pentecostals (Christianity) can be given who keep the worldviews relevant to today's needs.
The Great Teachers of the past revealed their teachings for past ages and prescribed no teachings at all for world peace or this age when the religions, nations and races are interconnected and intermingling.
So we have a new age dawned upon humanity with no guidance given in the Holy Scriptures of all the major Faiths. Man made attempts have been unable to transform the world and so we remain visionless and without direction with peace being elusive.
We have also had the great wars and many other terrible wars and violence, drugs, immorality and disunity between the nations, races and religions persist with no end in sight.
Although the Teachers such as Buddha, Christ and Moses died, the influence of their teachings lived on and was able to transform civilizations and individuals for centuries to come, even to this day.
But as They had left no guidance for our age as to how to deal with the conflicting creeds, races and nationalities we are divided on how to bring about unity and harmony.
However, They did not leave us empty handed. In all their Holy Books they speak of the last days or the end of the age and of another Great One to come at that time to deliver humanity from the abyss so to speak.
Christians await the Second Coming which is to usher in the Kingdom of God, a spiritual civilisation, Muslims await the Mahdi, the Jews, the Lord of Hosts, the Vaishnavite Hindus - Kalki, the tenth Avatar and the Buddhists Maitreya Amitabha Buddha.
Baha'is believe this is all referrring to the same Great Teacher
Would not another Moses, Buddha, Christ or Krishna have the spiritual influence to transform the world? Just as in the past their influence was so powerful it can even be felt today thousands of years later.
So is it not possible that another of these Great Teachers could revive and regenerate humanity spiritually? If Christ today still holds influenced over billions of Christians 2,000 yrs after His passing then if another Teacher with the same power were to appear today couldn't His Teachings also change the world?
Baha'is believe this Great Teacher has appeared and the Promised One foretold by all the major religions has come to bring peace and harmony to this divided world.
Baha'is also believe that the mystical power of These Beings is as such 'Be, and it is'. Whatever they proclaim and decree musters invisible spiritual forces to bring about the execution of Their Words.
For example. When Baha'u'llah uttered this word...
"The world is but one country and mankind its citizens" it was a 'mother verse' which brought forth the sciences, technologies and world communications to shrink the world into a global village.
Now, with the internet, the world truly is as one country and we as its citizens. We can communicate over voice and video all over the world with each other as if being in one another's home.
This, we believe is as a result of just one 'Mother Word'. To some this may seem unrealistic but if one will carefully examine Baha'u'llah's Words and compare them with movements born since and the direction of humanity since He revealed them they might find that humanity is moving towards His teachings unknowingly.
Great thinkers such as Vivekanada spent almost two months at the Green Acre Bahá'í School

Gandhi has numerous contacts with Baha'is and consulted them on occasion.

It is clear, I believe, that some of our greatest spiritual leaders have been influenced by Baha'u'llah's teachings.
