Christianity is well known for its emphasis on the expectation of the Return of Christ to set up the Kingdom of God on Earth. What’s not so well known is that Shia, a branch of Islam, has similar expectations regarding the Imam Mahdi, also known as the 12th Imam or the Hidden Imam. In reddit, a Muslim said the following:
I’ll just say one thing: When Imam Mahdi comes he will establish peace and justice once and for all. He will not change Islam and he will not bring a new religion.

But that very assumption means that it is possible that as thousands of years continue to come and go, the Muslim population may gradually come to the conclusion that the expectation of Imam Mahdi to come is unrealistic and that Islam is not a true religion after all.
That seems to be an issue Baha’u’llah, the founder of the Baha’i Faith, was aware of.

The vitality of men’s belief in God is dying out in every land; nothing short of His wholesome medicine can ever restore it. The corrosion of ungodliness is eating into the vitals of human society; what else but the Elixir of His potent Revelation can cleanse and revive it?
Could this loss of belief in God be a direct result of the prophecies of the return of Christ or of Imam Mahdi never coming to pass?
Why the Rapture is a bogus concept
A Critical Analysis of the Epistle of 2 Peter
We can understand that there was an actual time limit for the return of Jesus:
Matthew 16:28 King James Version (KJV)
Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
So Jesus should have returned by about 100 AD or so. Maybe AD 150 at the very latest. He didn’t, so:
Deuteronomy 18:22 King James Version (KJV)
When a prophet speaketh in the name of the Lord, if the thing follow not, nor come to pass, that is the thing which the Lord hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.
But the Quran clearly defines Jesus as a prophet of God. If Jesus failed to return in the time limit he himself gave, then according to Moses, he did not speak for God. If Jesus was false, so was Muhammad. If Muhammad was false, so were the Imams of Shia. So we shouldn’t expect the Imam Mahdi to ever return either. And since Baha’u’llah affirmed both Jesus and Muhammad as Prophets of God, he too is not one himself.
So where does that leave the Bab and Baha’u’llah? Well, the Bab claimed to be the Imam Mahdi, yet he was killed by a firing squad on July 9, 1850, thus failing to fulfil the promises of the Shias. And Baha’u’llah was said to be the return of Christ, but that seems illogical given the time limit Jesus gave. The Muslims, the Babis, and the Baha’is only seem to have credible faiths when you fail to remember that time limit for the return of Christ.
If you are ignorant of what Jesus REALLY taught (and failed to fulfil), you can be a sucker for anything. So to sum up:
- Jesus will never return.
- The Imam Mahdi will never return
- There is no religion after Judaism that is true.
- The desperate attempt by Baha’u’llah to stop the spread of atheism was pointless. Atheism is not a bad thing.
And those are my conclusions.
Dale Husband's Intellectual Rants 
In a two part YouTube video chart, I saw a Eschatology chart.
Part One Mainstream
Part Two Fringe
Each section is described and the particular denominations and theologians who advocate the view are listed too.The rows (from top to bottom) are: Pre Millennialism, A Milliennialism, and Post Millenialism. The columns (from right to left) are Futurism, Historicism, Idealism, and Preterism (subdivided into Partial and Full). The chart is further complicated by off spectrum and paradoxical views that make up the second video. Example: Catholics and Mainline Episcopalians are at the A Mill meets Partial Preterism part while more liberal ones are Full Preterism instead. Confessional Presbyterians are the Post Mill part of Partial Preterism. The Reformers themselves (Luther, Calvin, Cranmer, Wesley, etc.) were Historicist either A Mill or Post Mill. Lots of Evangelicals (Nondenom, Pentecostal, and Baptist) are Post Mill and Futurism with some Historicism instead rarely. I had to search most name of contemporary authors to find which denom they are.
that the promises of these religions fail is indeed a problem for them. They must keep changing their claims to continue ot exist.
Religion for Breakfast just did a video on eschatology and how the Rapture was invented by John Nelson Darby in the 1800s. Also, back to the Ready to Harvest eschatology chart, the Rapture is solely the domain of Pre Mill Futurism.
