is god willing to prevent evil, but not able? then he is not omnipotent. is he able, but not willing? then he is malevolent. Is he able and willing? then whence cometh evil? is he neither able nor willing? then why call him god?
god once said that without faith, i am nothing. U guys r all trying to prove he exists. if u prove he is real, then u guys just proved that he is not real.
