What do you do when people mock/criticize your religion?

[Firefly]

Im merely asking the most simplest of questions, "why do you believe what you do" and you cant answer it. Saying you believe in god but not being able to answer 'why', other than "its just what I believe", sounds to me like you're believing in something blindly.

I believe in what I do,because I do honestly believe that there IS God,and I believe,FROM THE BIBLE, that his son was sent here to wash away our sins.< This makes the second time I have told you,and yet it still isn't good enough for you to be consider 'an answer'. Now,if my answer doesn't 'satisfy' you,then I suggest you get off my back.
