It's a sin

'Christian focus is overwhelmingly on sin sin sin sin sin sin sin.  What a nasty preoccupation to have dominating your life' (Richard Dawkind, 'God Delusion').

'I am just a flawed human being, like anyone else' (atheist friend of mine).

'Nobody may pretend that there has been an elimination of the selfishness, and, sel-centredness of man' (Herbert Butterfield, University of Cambridge).

When asked by Joe Duffy, on the programme 'Spirit Level', if the concept of sin exists in Quakerism, Philip Jacob replied, 'Well, vaguely.  We don't specialise in trying to deal with sin, because it can often lead to guilt, and we don't think much of guilt.'

'God made him who had no sin to be sin for us, so that in him we might become the righteousness of God' (2 Cor. 5:21).

The above quotes reveal a couple of things.  Firstly, any rational human-being cannot deny the selfishness and self-centredness of our lives.  Secondly, liberal Christianity and atheism share a belief that it is better not to be preoccupied with thoughts about sin, and therefore offer no solution to its reality.  Thirdly, Christianity offers a unique solution to the problem of sin, so that we can both face the reality about ourselves and live free from feelings of guilt.
