Question I have for Christians.

[Quick]

I don't mean to be a dick when I ask this.

How do you rectify what should be an immense amount of stress that a Christian should feel knowing that whatever they do, they will never be "good enough?" As I understand it, to be a christian means to be in continual renewal of mind, body, and spirit (which I do not think is possible btw). While the problem of not being "perfect" might not be a problem felt explicitly by christians, I believe one of the core philosophies for why christians think atheist are atheists is because they want to be free from "responsibility" of the sin in their life. How does a christian rectify this in their own life?

And if I really want to get "out there" weird with it, I can ask how God can justify that because atheists simply want to rid themselves from a tieless and fruitless endeavor of renewal and as a result, be sent to hell?

I posted this inappropriately in the Questions for 'What is a Christians role on this forum'. I now realize my mistake, I was uninformed. Now I just ask what Christians think of this...
