Dear Shaker,
This doing good nonsense, I think that Christianity is ( or should be ) a very inward looking religion, a check and balance religion, a Christian should always be practising, practise makes perfect, not pointing the finger, they should never say, I am a better person than you, rather they should be saying, how can I become a better person.
Alan is halfway right, a good Christian, a practising Christian has Jesus constantly on his/her shoulder, of course Christians are human just like atheists.
