He wants us to believe that we are born sinful, that we were evil and needed saving even before we had done anything. Our path to salvation lies in service to God, selfless self-sacrificial service to God and his dogma. Fortunately for God, Original Sin guarantees that we will always feel under threat. We will always be unclean and in danger of suffering hellfire. To make quite sure that our personal responsibility is destroyed, and that we put ourselves in God's hands for him to mould us as he wishes, God and his moronic minions repeatedly tells us that Jesus Christ is the Way and that he died for our sins.
Redemption lies through faith and obedience.
Notice what happens when Christ supposedly died for our sins. His act brought about our possibility of salvation. I am responsible for my own actions. Nothing that I do can take away the fact that someone else acting in a certain way, and nothing that they can do can absolve me of my own responsibility. Original Sin and salvation by Christ are both deeply offensive ideas to me and to all extropians who value individual responsibility.
