Miserable Hope! (Only a way out from real trouble is by having help from true Messiah.)

Revelation 13:13-18  says “[13] And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men, [14] And deceiveth them that dwell on the earth by the means of those miracles which he had power to do in the sight of the beast; saying to them that dwell on the earth, that they should make an image to the beast, which had the wound by a sword, and did live. [15] And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed.[16] And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: [17] And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. [18] Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six (666).”

Is it possible that a lot of people worship God by their mount, but their hearth fail to accept Satan?  

In order to help people. God keeps His promise for the true Messiah.
But, people reject God's prophecies.
Then, people should learn their lesions in a hard way.

4Ezra1:4-6 says “[4] And the word of the Lord came unto me, saying, [5] Go thy way, and shew my people their sinful deeds, and their children their wickedness which they have done against me; that they may tell their children's children: [6] Because the sins of their fathers are increased in them: for they have forgotten me, and have offered unto strange gods.” 

Jeremiah 2:19 sats “Thine own wickedness shall correct thee, and thy backslidings shall reprove thee: know therefore and see that it is an evil thing and bitter, that thou hast forsaken the LORD thy God, and that my fear is not in thee, saith the Lord GOD of hosts.”

Isaiah 43:10-11 says "[10] Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me. [11] I, even I, am the LORD; and beside me there is no saviour."

Isaiah 32:17 says “And the work of righteousness shall be peace; and the effect of righteousness quietness and assurance for ever.”

Interesting facts.

Why did many God’s prophets in different time and places of the world had their similarly prophecies dedicated to The True Messiah? 

One possible reason of answering the question is that God told the prophets to write them down which is clearly indicated as in;

2 Esdras of the Apocrypha, 4Ezra.15 stated [1] Behold, speak thou in the ears of my people the words of prophecy, which I will put in thy mouth, saith the Lord: [2] And cause them to be written in paper: for they are faithful and true. [3] Fear not the imaginations against thee, let not the incredulity of them trouble thee, that speak against thee. [4] For all the unfaithful shall die in their unfaithfulness. [5] Behold, saith the Lord, I will bring plagues upon the world; the sword, famine, death, and destruction. [6] For wickedness hath exceedingly polluted the whole earth, and their hurtful works are fulfilled. [7] Therefore saith the Lord.

There were some prophecies that God secretly granted only to The True Messiah, but not for other.

Amos.8:12 says “[12] And they shall wander from sea to sea, and from the north even to the east, they shall run to and fro to seek the word of the LORD, and shall not find it.”

Religion believes about God:

Every major religion's sacred text indicates "Who" God Is, even Buddha, the founder of Buddhism has answered the questions asked by Sakra, the Mighty God, who is the king of gods in three worlds?"  Therefore, it is clear that Buddha did not ignore the indications about God. But, Buddha taught monks and people that one should depend on oneself and not depend on God.

The Holy Bible; The King James Version (KJV) and Nostradamus’ prophecies are used as main unlock keys for verification truth of the True Messiah. 

Supporting information such as from selecting the sacred text of each religion and comparing them in regards to the coming time of the world's last divine representative, some of them may be selected and used for the verification purpose.

Divine titles used by major world religions.

Major world religions sacred texts have been compared, and Scholars agree that there are indications that similarities do exist among all the different sacred texts profiles and descriptions of their last coming divine person, who comes to bring about true world peace and to fulfill God’s divine will on earth. He will be manifested with the righteousness of God. He will defeat evil, and establish the kingdom of Heaven on earth. The divine person indicated by each of the religion's texts, might be or might not be, we are not able to judge, but God knows who the divine person is.
