"As the Reformer proceeded on his journey, he was everywhere regarded with great interest. An eager multitude thronged about him, and friendly voices warned him of the purpose of the Romanists. “They will burn you,” said some, “and reduce your body to ashes, as they did with John Huss.” Luther answered, “Though they should kindle a fire all the way from Worms to Wittenberg, the flames of which reached to heaven, I would walk through it in the name of the Lord; I would appear before them; I would enter the jaws of this behemoth, and break his teeth, confessing the Lord Jesus Christ.”— Ibid., b. 7, ch. 7. GC 153.1"
"Then Paul answered, What mean ye to weep and to break mine heart? for I am ready not to be bound only, but also to die at Jerusalem for the name of the Lord Jesus."
Both passages depict a willingness to face persecution and even death for the sake of Christ. Luther's bold statement about walking through fire and confronting the 'behemoth' echoes Paul's readiness to die for the name of the Lord Jesus in Acts 21:13. The courage and commitment to Christ are the central thematic parallels.
