Which is precisely what he has done. People let him down, not God, but he has turned his back on God and placed his faith in humanity. His own words.
Jesus told us we would have trouble in this world. We were never promised a world where innocent babies are never stillborn, or born completely normal. Good, faithful people are not being punished with a tragedy, nor is anyone exempt from such a tragedy. My family has personally lost eight babies to miscarriage or premature birth.
As for the man who beats his wife, he should have been disciplined and then educated by the church. And if that didn’t work, put out of the church. The failure is his, not God’s.
Yes, he's placed his faith in humanity. Good luck with that!
This comment of his is telling:
"Certain ways of thinking about ourselves and life and other people and these beliefs and mindsets, these narratives that have been indoctrinated into us can be very saboteurial into our journey of wanting to be at peace with ourselves and to live a life of liberation," he said.
If a person is truly trying to improve and to live as a good person, he's going to have to look directly at his imperfections and that's a hard thing to do. It would be much easier to accept one's imperfections as inevitable in order to have "inner peace" than to work at correcting them.
