What the fuck?!
Why do you fear living freely? Why do you surrender yourself to religion so easily? Don't you think that since God has not made your purpose on earth so obvious, he probably intends you to find a purpose YOU believe in and not blindly follow what some book says? Since there is no apparent purpose for our existence yet, why do you cling on to false hopes offered by religion?
What do you know for certain about the "afterlife" that you believe in religion so much? Do you know any specific details? Do you know on what exact basis does God throw you into heaven or hell? Do you know what acts he considers a sin and which ones he consider otherwise?
