Hitler was a special kind of evil. Not unique, but special. I don't believe that one that has convinced themselves to do what Hitler did and directed those under him to do has the desire or capacity to hear from God. The Apostle Paul started on a similar path from a different viewpoint. Zealous for God, but blinded to what his scriptures taught, while still known as Saul but Jesus was able to get his attention in a way that points to God changing people. The author of the hymn, "Amazing Grace" was a ship's captain for many years. He made many voyages to and from Africa loading people who had been captured and enslaved by people in Africa and transporting them to markets where they were sold to people in Europe and the Americas among other places. He had been part of this endeavor for many years. Jesus found him and made him a new creation. The transformation caused him to realize that his role in this evil was also evil. "Amazing Grace" was his testimony to God's mercy in extending grace to those that don't deserve mercy or grace. He was so completely changed, that in his last years, he developed dementia and no longer remembered his past. When family, friends, and curious visitors would go to see him, he would greet them with, " Hello. I don't know who I am and I don't know who you are, but I do know that I was once a great sinner but God saved me."
