Definitely I believe in God...
There are many reasons to believe such a way, no one thing come along. Obviously there's a plan, and the whole thing is going according to the plan. There is only one God, but there are many names. Some people call Allah, some call God. So we have to read more documents to follow the right way. But the existence of God is out of questions.
So there is satan? Angels Devils? heaven? hell?
Why are not there prophets these days?
Why has not someone ever shown a photo or video of an angel? demon? heaven? hell?
Are many years and never seen a single photo or video? Even the dinosaurs I've seen photos and videos, but I've never seen photos and videos of angels.
Do not you think it's all very strange?
The answer to your questions is found in the Revelation:
18 I warn everyone who hears the words of the prophecy of this book: If anyone adds anything to them, God will add to him the plagues described in this book. 19 And if anyone takes words away from this book of prophecy, God will take away from him his share in the tree of life and in the holy city, which are described in this book
In other words, everything that has been written has been written. All the pictures-by-description have been shown. The word "prophet" has changed because of this.
In the past, before the time of the Revelation, a prophet foretold something that was going to happen.
Now, because everything has been written that is going to be written, a prophet can't do what those old prophets did. Modern-day prophets don't tell about the future. They simply express what has already been said. The churches and Bible studies are filled with loads of prophets, expressing what has already been said.
