Believe me when I say I had both of these, and applied them earnestly in fervent & frequent prayer, study and self-denial for years. What did it get me? A whole lot of disappointment and confusion. The scientific world view has not brought me anywhere near the false happiness of believing I could become a blissful immortal, but it has at least given me firm ground to stand on, and to have rock-solid reasons for what I can still appreciate.
I'm glad for anyone who can experience a happy daily life in a religious worldview, but having the prideful audacity to claim that it is equally available to everyone (and by implication, that anyone who doesn't have the same response is a liar) is either dangerously ignorant or outright evil. I have known your kind before, because I was one. Think about it.
To be honest, this sounds like some b.s. my mother picked up from 'Christian' radio (i.e. GOP propaganda meets X-files) and terrorized the kids with. There was a book called the beautiful side of evil that informed a lot of the kind of thinking you describe, and it is 100% purely anecdotal assertions from one person with extreme views. If you look across the spectrum at more individuals, those assertions fall apart pretty quick.
