...but I think you've already been given the workings of an answer in both your assertion that you feel inundated and bombarded by conflicting claims and instructions from different religions, and the suggestions of others that "by their fruits shall ye recognize them".
Think about it... if you see someone who is a Muslim showing good fruits, and a Christian showing those same fruits, and a Hindu and a Jew and a Taoist - all showing those same fruits... using your imagination, what does this tell you? Either a) they're all valid or b) people can achieve enlightenment through their own humanity, and any philosophy or religion can serve as either a leg-up, or a stumbling block, depending how it's used.
As for how we can know that God/s is/are loving and want that, well... that can be explained as well. I just don't have time or inclination right now to do so. Try this...
But it seems your primary motivation for and potential use for religion is getting yourself to heaven, right? Again... pretty alien to me... but good luck with it Heaven and hell don't really feature much in my philosophy, except as states of mind that we do to ourselves. My motivation is more about improving life here and now, for myself and for others. Well, that's what it was in the beginning... it's now just love for love's sake. I'm just stating that for the record... I don't expect you to understand, sympathize or agree with it.
Given that our dominant functions are the exact opposites of each other, it's pretty unlikely that in the course of an internet forum thread, we're going to be reconciled entirely. But try and focus on that being the source of our misunderstanding, rather than just putting it down to me being an idiot
