When reading through a book...
When reading through a book like Foxe's Book of Martyrs or DC Talk's Jesus Freaks, you will often find stories of Christians who met extreme circumstances like imprisonment, torture, and execution with an extraordinary sense of peace and even tranquility. People were known to pray for their executioners while being burned at the stake. One man was even reported to have wrapped the chain binding him to the stake around himself. Our sense of self-preservation and survival is often so strong that to abandon it like these martyrs did is almost unimaginable.
