It can save you if it brings about a moral and ethical reformation in you, and that’s for being good. Most Religions want unity through their individual diversity. But If it makes you cunning, selfish, self-praiseworthy, proud, prejudice, and so on so forth of this sort; the religion or even rational philosophy shall be of no use to you.  To be frank, anything which elevates in you a sense of divinity or self appreciation will cause you to become a better human being.
