The thing is, we humans are most loving, most patient, most kind and generous when we become rocked to our core by all that has been given to us.
Romans 9:22 tells us how Creator God is even kind and generous to those who are destined for destruction. Their rejection and denial of His kindness is symptomatic of those who are determined to travel the road to hell all the way to its inevitable end.
An atheist told me a couple days ago that it's arrogant for Christians to think they have something to give. In fact, there is no truth that we could give to someone else that we don't desperately need ourselves, or that we haven't received ourselves. We are the most humble and gentle when we've seen that others in need of love and mercy and patience and forgiveness are just like us.
Unlike atheists who hold their perceived virtue in high esteem, and who therefore think they've “arrived,” making them impatient and merciless (witness the atheism+ kerfuffle), Christians have been shown their inner self, and it's not a pretty sight. We realise that we are all sinking and sinking fast. We realise that we all need the love that is found only from One source. And His goodness and generosity is like a stream leading back to that Source.
