How do you know that you picked the right religion? A Muslim talks just as passionate about the Quran as you talk about the Bible. The Vikings here in Norway spoke about their God just as passionate as you, the same did the Greeks. How do you now that you are right, and not the others? There can only be one Truth, and there is a lot of religions out there claiming to have it, that means someone got it wrong, if not all.
How do you know that your book, the Bible, is the Truth? I know it says in the Bible, that is is the Truth. But if I write a book today, saying it is the Truth, is it the Truth then? No, it is not. We don't even know exact when the Bible was written, and it has been translated several times before it ended up at your house written in English.
The bible says that there was a snake that was talking, there are no snakes that talks today, where did they go? How did one man build a wooden boat housing two of each animal in the entire world? We could not even do that today with steel. What did the animals eat since animals like to eat other animals? How did one man clean up the shit from all the animals, while giving them water, food, while steering the boat, in a storm/flood? How did he pick up the kangaroos? Did he have a dock ready in Australia for this enormous boat? Or did he swim to land, catch them, then drag them back to the boat? How did he catch the leopard and tigers, they are pretty fast, aren't they? Hmmm....
Sorry, I just get a little uncomfortable when people use a book that has no grip in reality, to regulate reality. It makes no sense at all.
