so we are on earth to redeem ourselves from original sin and earn a place into heaven?
why did god allow sin to exist in the world in the first place?
why have this existence that's riddled with pain at all?
Argh. i try hard to avoid questions on religion ... especially on the innernet but here we go.
God didnt allow sin to exist in the context you're asking the question. Satan said he can do things better so god let him .. sin is a product of Satans poor management skills..
Once again.. this existence isnt riddled with pain .. thats satan's doing... if yo read the story of Job you will understand what that means ...
remember Adam and Eve didnt have sin at first living in the garden.. it want until satan came along did man experience sin
Satan knows god is/was right... his only perpose now is to make you/us/we curse god. thats where all the pain comes from. the more pain we see the more we say their is no god...
