Prophets and Messengers would come with clear proofs. Of their evidence were real life eventful miracles that proved God trusted them with immense power and immense knowledge others didn't have.
Now if the Guides are followed, there is no reason, for these miracles to come to an end. Guidance if followed by humans, would prove to be fruitful.
The reason why Deism or even Atheism seems more likely than religion in these dark times, is quite simple. We humans have made a mockery of God's guidance and sabotaged his Messengers and abandoned his guiding kings on earth.
Over time, divisions appear normal. No unity but further division and hate over disputes over how to refer to God and the founder(s) of the religion, becomes detrimental for humans.
The opposite of guidance but rather, the book is misinterpreted as in the case in Islam, and the Sunnah filled with fabrications that no one in their sane mind can believe a Prophet of God would teach but instead we inherited insanity generation to generation believing in lies that are obvious evils attributed to the Prophet.
In this case, the reason why miracles are not in the open, the reason why there isn't present guide in the open to show miracles, but now is hidden and if miracles to be shown, to be shown not in public...
The reason why miracles are not in the open is quite simple. We sabotaged the Captains that navigate by the name of God and are misguided almost beyond repair.
Religion in this case, seems, to be a catastrophe. It doesn't matter if Mohammad or Jesus or Moses or Abraham are all true guidance, it appears that, guidance has failed.
In other words, Shiites can talk about the need of divinely appointed kings (Imam Ali, to Imam Mahdi), prove it all they want, it looks more like the powers that be, have funneled it and fabrication of Quran can be even seen in light of that, to funnel our efforts into waiting for the Mahdi.... and it can appear religion was just a power game by elite sorcerers for example.
To prove religion in these dark times is tougher then ever, because, all the purpose of Messengers you can talk about, you have to justify why it didn't happen.
The purpose of guidance is to guide, yet it didn't. The purpose of kings was to established God's Authority and light, yet there were killed and murdered and their followers oppressed.
In other words, because of our insolence, or lack of effort to help one another, because of our lack of response, we even make it appear that there was never guidance from God, and if arguments for religion against Deism are sound, it appears Atheism is more true in this case.
The epidemic of insincerity towards God and his guides, is ever so present. We are in dark times.
Miracles in holy books were talked about in a way, they were here to stay. The fact we don't have them, is because something is preventing God from sending them. That is his mercy, so that he doesn't destroy us like Noah's people, he is delaying it.
But if believers are oppressed, and the oppressors are not fought or stopped, God will have to bring the Mahdi in a worst case scenario.
The Mahdi, Jesus, Elijah, all meant to come back on good terms. But now they will be coming back on worst terms, and I fear the destruction of great portion of the world and cities... "and not a city (that disbelieves) except we will destroy it or punish it a severe punishment before the day of judgment...."...…
We think we are immune to God's wrath despite his ever warnings of destroyed cities or nations of the past.
The Mahdi and Jesus and Elijah return are supposed to be good news. But it also a warning, and it could be with little good news and mostly warning bad news.
The warning aspect - we walked the path of his warnings. I fear, if the oppressors are not stopped, you will force God's hand.
The oppressors must be stopped and not supported nor silently watched, lest, we face God's wrath. Even the Mahdi which was suppose to the greatest mercy to humanity, will become, like Noah who was originally meant to be a mercy and grace from God, a means of God's wrath and destruction.
I rambled a lot. I know. Sorry. But I wanted to speak and ramble through my heart here. Less intellectual, more just frustrated rambling of our situation.
