Yes , this is a tough area, but it seems to me that it is also where mankind most fails. Because all sins can be forgiven, but we find it hard to forgive others , and this was the issue Jesus made most about forgiveness, acknowledge yours and forgive others their sins
This alone accounts for most problems in society, because even those who are Christians act as if they are better than others . And if even the best of christians cannot be as humble as they should , what do we expect of atheists. But we are supposed to not woorry about what others think about us, only God.
I know it is easier said than done . The majority are unaware they should be doing it at all.
Most sermons try to get that across every sunday.
Sometimes people get mad at me for ridiculing myself, or saying I am a hypocrite , or saying I am sorry too much.
I just say forgive them for they do not know what they are saying. Just as I say and do sinful things and wish they would forgive me.
There is a constant that runs through most Church fathers, and that is they deny being worthy of our admiration.That they are sinners the same as us, and they think they need us to help them.
