Martyr Trophimus and 14 Others in Lycia:  if we need an example that sin blinds the sinner we only need to look at these martyrs.  They were thrown in a fire by the pagans but were unharmed and walked out.   The pagans then beheaded them.  Normal people would either have recognized the power of God or run.
