I wonder what percentage of these people would claim that they themselves are not sinners. My guess is... most of them.
It’s mostly unchurched ignorance but not all of it, much is hatred of Jesus.
Most non-Christians believe in the good-bad balance. If you do just a tiny more good than bad, you’re in.
Like many of the religious Christians who try to condemn other by pointing out the "Go and sin no more" phrase Jesus spoke to the woman.......
Those folks are either the biggest hypocrites in the world (akin to the pharisees) or they are really deluded into thinking that certain sinners are actually capable of ceasing all sinful acts...
