How to get reliable informations about God

[Sigurd]

All the topics about life, God, life after daeth, souls ... are very important to everyone, I guess. But it is really hard to get relyable information.
What do you think is the way to get trustable information?

It is not easy to get correct information (note that I am not saying true) because of enmity between religious and non-religious, between sects or denominations and across faiths. In addition to that are the many degrees of maturity/understanding of individuals in the different faiths.
The questions you have are more or less directed at religion and should be answered by religion.
The way I got information was going to the different denominations in question and ask. It is however important to verify the answers especially if the answers are opinions of individuals (ref: maturity and understanding). The best way is to get official pamphlets and or official books.
The worst thing you can do is to get information about the Catholics from the Protestants and vise versa. The likelihood of getting incorrect information is quite high.
Go to the source.
That being said it is nearly an impossible task to get a complete overview of one of the topics you mention. Just within Christianity you could spend a lifetime just to compile definitions of God.

[edit]: I didn't notice this was a poll...
I have never experienced the supernatural of religions and hence must rely on what I can read and answers I get to my questions.
The combination of book sources and learned men in the form of scholars and teachers are probably the best way to gather information.
