How do you know?

Excuse the heresy coming from an innocent agnostic, but how do you know that your religion is the 'right' one? Were you raised that way? Did you have an epiphany? Are you compelled to worship out of fear of eternal damnation or worse, oblivion? Do you "just know?" Or do you accept the fact that either all religions are right or none of them are? You see, as an agnostic I am free to admit that there are some things I do not yet know. I invite you to share your experiences here, so that I and others may gain some valuable knowledge by listening to you.
