Did God promise people?

Yes! Why the only thing that has abounded on earth at the present time is the tribulation. Those who hope for the advent of the millennium should have questions about God’s promises.

Where is the earthly paradise or zeon? What is the unity of God? How shall all people be all righteous?

How many people realize that before coming of the true Messiah or other names as indicated by different religions and/or languages such as last Buddha {Pali = Metteya (read) / Metteyya (write) or Sanskrist = Maitreya}, Kalki, and True Man would be the time of tribulation and confusion?  Many passages describing the last days are telling us that natural disasters, famines, plagues, and wars will abound all over the world. Some examples of scriptures are shown as:

But understand this, that in the last days there will come time of stress.  For men will be lovers of self, loves of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, inhuman, implacable, slanderers, profligates, fierce, haters of good, treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, holding the form of religion but denying the power of it.
Christianity. 2 Timothy 3.1-5 

And when the world is fulfilled against the unjust.  We shall produce from the earth a Beast to face them: he will speak to them, because that mankind did not believe with assurance in Our signs.
Islam. Qur’an 27.82

Behold, speak thou in the ears of my people the words of prophecy, which I will put in thy mouth, saith the Lord: And cause them to be written in paper: for they are faithful and true.
Fear not the imaginations against thee, let not the incredulity of them trouble thee, that speak against thee. For all the unfaithful shall die in their unfaithfulness. Behold, saith the Lord, I will bring plagues upon the world; the sword, famine, death, and destruction. For wickedness hath exceedingly polluted the whole earth, and their hurtful works are fulfilled.  Therefore saith the Lord,
Judaism and Christianity. 4Ezra 15.1-7 (2Esdras) KJV

Miroku (Metteyya / Maitreya), the Great God, come forth, endowed with the great strength of the three in one Fire, Water, Earth (Earth quake).  Miruku, the Great God, from the old has planted heaven upon earth. Miroku, the Great God, even as come a thief, has secretly been born below. 
Sekai Kyusei Kyo.  Inori-no-Shu.

God’s promise is not in vain.

What are the scriptures speak of a coming divine person, the true Messiah who will consummate the fulfillment of the divine will on earth? Who is the true Messiah? Is he the representative of God? Is he God’s servant? Is he God himself? Is it all a mystery?
Where is the true Messiah that is prophesied to come at the millennium as many scriptures indicated?
Many scriptures that are commonly recognized indicate what God’s promises are, a couple of examples that indicated this are:

 “peace there shall be no end.  … The zeal of the LORD of hosts will perform this.”  Judaism and Christianity. Isaiah 9.7

“The Great God, even as come a thief, has secretly been born below.” 
Sekai Kyusei Kyo.  Inori=no-Shu.

When the law declines and purpose of life is forgotten, I manifest myself on earth.  I am born in every age to protect the good, to destroy evil, and to reestablish the Law.
Hinduism. Bahgavad Gita 4.7-8

And the Lord shall be king over all the earth: in that day shall there be one Lord, and his name one. 
Jadaism and Christianity. Zechariah 14.9

Could one tell the truth? 

Yes. The one has zeal (Isaiah 9.7) of God could tell the truth.  He is the true Messiah. He has name in different languages, but his name is one (Zechariah 14.9).

Does true Messiah exist?

The true Messiah does exist at he present time as most world scriptures and prophecies stated. 

Is the promise of God truth?

“For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, God formed it to be inhabited: I am the LORD; and there is none else. I have not spoken in secret, in a dark place of the earth: I said not unto the seed of Jacob, Seek ye me in vain: I the LORD speak righteousness,

I declare things that are right. Assemble yourselves and come; draw near together, ye that are escaped of the nations: they have no knowledge that set up the wood of their graven image, and pray unto a god that cannot save.

Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me.

Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else. I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return,
That unto me every knee shall bow, every tongue shall swear. Surely, shall one say, in the LORD have I righteousness and strength: even to him shall men come; and all that are incensed against him shall be ashamed.
Judaism and Christianity: Isaiah 45.18-24

Conclusion: God spoke open and with righteousness, God created earth and the living soul, and He did it not in vain. “There is no God else beside me; a just God and a Saviour; Look unto me, and you will be saved, all the ends of the earth.  Anyone that is against God shall be ashamed, I have sworn by myself.”  Now is the time that we should seriously consider God and search for his truth.

God is not just the God that is described and known to us from only the scriptures.
What the above statement means, is that God and His ways are not limited by what is written in the scriptures. God's existence and His ways are established in truth, and this can be proven in a verification lead by the divine one who knows the secret of God.

“Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man. For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.”
Judaism and Christianity: Ecclesiastes: 12.13-14

To whom is the ability given to clarify the true answer to God’s mystery?

Zechariah 14.7-9 provided us the answer, and his name is one, who is the True Messiah (Messiah is also known by other names as indicated by the different world religions and prophecies such as Metteyya or Maitreya Buddha, Kalki, and true man).

“But it shall be one day which shall be known to the LORD, not day, nor night: but it shall come to pass, that at evening time it shall be light. And it shall be in that day, that living waters shall go out from Jerusalem; half of them toward the former sea, and half of them toward the hinder sea: in summer and in winter shall it be. And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one
Judaism and Christianity: Zechariah: 14.7-9

Is God going to magnify himself to unlock the truth on earth?

No! Comparative studies show that God’s representative would be given the ability to do God’s work for God. God will provide the Messiah with His (God's) own image to honor his representative. He, whom is prophesied to be the last divine representative of God, the one whom will bring true world peace and happiness to all that lives on this earth, and known by many divine titles per different religions and languages but most popularly known as the Messiah. The one that is known by many divine titles such as Christ, Kalki, and Metteyya or Maitreya.

Is God the Messiah?

No!

Who is the Messiah?
The Messiah is God’s righteous servant, whom God will provide with His (God's) own image and his authority in order for the Messiah to interface with people in front of God.
(God's image means that the true Messiah will have the name of the mighty God, as described in prophesies of many religions and indicates that he is the divine person whom can be verified by physical evidences.)
Isaiah 53.10-11 provides us with some insight about the Messiah..
“Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand. He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.” (He means Messiah)
Judaism and Christianity: Isaiah 53:10-11

What is the link between God and the True Messiah?

God and the Messiah are linked by prophesies of many religions that are recognized around the world.

Why does the Messiah need to be here on earth?

The Messiah is chosen by God to perform God’s work for bringing into existence, true world peace and happiness that continues without end, as indicated by most world religions and prophecies, such as, those of Nostradamus, which indicated that the world of the new millennium (A.D. 2000 and beyond) is the ideal world, a world without evil, a world where God’s sovereignty is fully manifest. These passages clearly regard it to be true, that, the Kingdom of Heaven will be a vision of God reigning on earth.

Is it possible for all people worldwide to agree on what is truth?

Yes! The one, who has the zeal of God (Isaiah 9.7), has the ability and the purpose to reveal the truth's of God. Who is he?

“For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counseller, The mighty God, The everlasting Father, the Prince of Peace.
Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.”
Judaism and Christianity. Isaiah 9.6-7

There are many prophesies that describe, peace on earth. The following are a few examples:
The victorious World-renovator and his helper shall make the existence renovated ageless, deathless, unputrifying, incorruptible, ever-living, ever benefiting, ruling at will. The dead shall rise up, life shall prevail indestructible, and existence shall be renovated at the will of God.
Zoroastrianism. Avesta, Zamyad Tasht 19.11-12

Now is the gracious Lord’s ordinance promulgated. No one shall cause another pain or injury; All mankind shall live in peace together, Under a shield of administrative benevolence.
Sikhism. Sri Raga, M.5, P.74

The Kingdom upon that Day shall belong to Allah. He will judge between them. Those who believe and do good works shall be in Gardens of Bliss, but for those who disbelieved Our verses and belied there awaits a humbling punishment.
Islam. Qur’am 22.56-57

What is the different between our times and the messianic times?
Judaism. Zohar, Genesis 139a.

When the Golden Age begins, those left over from Kali age (Age of destruction) will be the progenitors of the Golden Age. All four classes will survive as a seed, together with those born in the Golden Age, and the seven sages will teach them all dharma (true righteousness). Thus there is eternal continuity from age to age.
Hinduism. Linga Purana 1.40

Listen attentively with hearty. A man whose spirit shines brightly, a man whose mind is completely unified, a man whose virtue excels everyone-such a man will truly appear in the world. When he preaches precious laws. All the people will totally be satisfied as if the thirsty drink sweet drops of rain from heaven. And each and every one will attain the path of liberation from struggles.
Buddhism. Sutra of the great. Accomplishment of the Maitreya.

Confucius said, “If a Kinly man were to arise, within a single generation Goodness would prevail”
Confucianism. Analect 13.12
