"Ephraim Stoltzfus, raised in the Amish culture, was disfellowshipped from his community for having the audacity to share the gospel with the lost, conducting Bible studies with his family, and for reading the Bible in English. As he studied the Word, he realized that that his leaders’ traditions didn’t exactly line up with Scripture."
I saw this show the other week, this Amish man and his family were born again, and later would leave the Amish church. Before then they were shunned for their more evangelical beliefs and for witnessing the gospel. It is a few years old but I found the story interesting, even if he does not know about Ray Comfort yet, I think this man's heart is in the right place. I have talked about how the Amish religion before on here and how they teach a false gospel, they do not believe in witnessing to the lost. There are other Amish who do become born again, and end up having to leave the Amish
