(This may offend some sincere 'christians'. Sorry in advance.)
Can you, as a human, stop yourself from breathing?
I have always thought that one of the basic teachings of 'christianity' is the concept that we are "mere sinners"...riddled with guilt and not worthy of god or life...undeserved kindness has been shown to us etc...
BUT, we have no control over that, just as we have no control over breathing air!
Now sins are described as "falling short of perfection", not just outright wicked acts...but just being a normal human means we are a 'sinner'.
SO, are we guilty for something we can do nothing about??
Is that fair and just??
