John Bunyan's readiness to die

I did often say before the Lord, that if to be hanged up presently before their eyes would be means to awake in them and confirm them in the truth, I gladly should consent to it. (DG)

John Bunyan was ready to be hanged in the gallows, not for anything evil he had done, but if it might awaken and confirm His people in the truth. Is it any wonder that God used Him so instrumentally?
