The moral danger of the day is not the existence of sinners. It’s that sinners don’t believe in the existence of sin.
We see this so often. Many people, especially young people are self-describing as “nones.” But many polls also indicate that a large majority still believe in God. They just don’t believe in sin. Or in Hell. Or all those rules-things.
The more we pretend God is just like us, the less we try to become like Him.
