Good exists - a Catholic comments

[Barry]

The problem for humankind is that they don’t want to feel responsible to God, despite knowing in their hearts God exists. 

What does this mean? How are people who don't believe in god irresponsible, but people who believe in god are responsible?

What is it that believers in god think that non-believers in god do that is so at the same time awful and great that they don't want to stop doing it to become responsible?

I didn’t say atheists are “irresponsible”, I said they don’t want the burden of being “responsible”. Being a believer in God actually means one knows one is “responsible” for one’s actions and decisions. I don’t believe in “once saved always saved.
