I believe in God.<quoted text>
In that case, you should just state it's a belief and not fact. Saying something is fact without presenting evidence to support it is pretty much lying. Stating something is fact is the same as saying you have evidence you can present to back it up.
I know God is real, I've felt His hand & heard His voice.
I can't provide evidence of that anymore than you could provide evidence of the feeling in your palm when you shake someone's hand.
