Yeah, and no loss for God and Baha'u'llah. They tried to show us. We are just too flawed to listen. Now God will have to darn near destroy the Earth again to make us see that he is real. Wait, isn't that kind of proving that he is real to all people? But causing bad things to happen us all, including some Baha'is probably, is the best why to "prove" that he is real? He couldn't just say something? I mean directly, not through a go-between.
You seem to think God and Baha'u'llah have a need for us.
I know we have answered your question many times about why God does not talk directly to Humanity, but via a Messenger.
The messenger was created to endure, this is no better shown than in the Fire Tablet. Fire Tablet
Baha'u'llah, in this tablet, asks many things of God, much like when Jesus was on the cross and asked of God why he had forsaken him.
Then Gods reply is given -
"O Supreme Pen, We have heard Thy most sweet call in the eternal realm: Give Thou ear unto what the Tongue of Grandeur uttereth, O Wronged One of the worlds!
Were it not for the cold, how would the heat of Thy words prevail, O Expounder of the worlds?
Were it not for calamity, how would the sun of Thy patience shine, O Light of the worlds?
Lament not because of the wicked. Thou wert created to bear and endure, O Patience of the worlds.
How sweet was Thy dawning on the horizon of the Covenant among the stirrers of sedition, and Thy yearning after God, O Love of the worlds.
By Thee the banner of independence was planted on the highest peaks, and the sea of bounty surged, O Rapture of the worlds.
By Thine aloneness the Sun of Oneness shone, and by Thy banishment the land of Unity was adorned. Be patient, O Thou Exile of the worlds.
We have made abasement the garment of glory, and affliction the adornment of Thy temple, O Pride of the worlds.
Thou seest the hearts are filled with hate, and to overlook is Thine, O Thou Concealer of the sins of the worlds.
When the swords flash, go forward! When the shafts fly, press onward! O Thou Sacrifice of the worlds.
Dost Thou wail, or shall I wail? Rather shall I weep at the fewness of Thy champions, O Thou Who hast caused the wailing of the worlds."
That is a hard pill to swallow, would you not agree? How would you like the path offered above? Baha'u'llah has also said, how many would choose that path, unless they are of God!
Baha'u'llah then answers the above with this;
"Verily, I have heard Thy call, O All-Glorious Beloved; and now is the face of Bahá flaming with the heat of tribulation and with the fire of Thy shining word, and He hath risen up in faithfulness at the place of sacrifice, looking toward Thy pleasure, O Ordainer of the worlds.
O ‘Alí-Akbar, thank thy Lord for this Tablet whence thou canst breathe the fragrance of My meekness, and know what hath beset Us in the path of God, the Adored of all the worlds.
Should all the servants read and ponder this, there shall be kindled in their veins a fire that shall set aflame the worlds." Bahá’u’lláh
