Have you considered Calvinism?
Lots of people will hate what you believe and accuse you of believing things that either are not your beliefs, or that they believe too, but word it to sound evil the way you believe it and good the way they say it.
On the plus side, God is responsible to do all of the heavy lifting when it comes to salvation.
[I am just kidding.]
As a serious answer, 'test the spirits' is good advice.
Start with what is knowable about God without any supernatural revelation.
Does whatever has been revealed agree with what is knowable from life and creation?
If no, then that should make you nervous.
If yes, then that should give you comfort.
[For the record, Calvinists believe that God chooses whom he chooses, so It is not on my shoulders to convert anyone.]
