From The Life of John Thompson:

I started to return to the doctor’s, when suddenly my steps were arrested, and a voice seemed to say, don’t go any farther in that direction. I started on again; but the same feelings returned with redoubled force. So I turned upon my footsteps, and these feelings left me.  I made a third attempt to go home. But I was more effected than before. I became nearly blind, my head swam, and think that had I still persisted to go forward in that direction, I should have fallen dead, in the road. I entered Uncle Harry’s house and he said, “the whole plantation, at the doctor’s, is in an uproar about you, as they say you have been giving passes to slaves, to help them run away. They have offered three hundred dollars for your arrest; so the patrollers will be looking for you.” Now my morning’s feelings were fully explained. I knew it was the hand of God, working in my behalf; it was his voice warning me to escape from danger. I fell upon my knees, and with hands uplifted to heaven, related all the late circumstances to the Great King, besought his protection, and solemnly promised to serve him all the days of my life. I received a spiritual answer of approval; a voice like thunder seeming to enter my soul, saying, I am your God and am with you; though the whole world be against you, I am more than the world; though wicked men hunt you, trust in me, for I am the Rock of your Defence.
