As John Wesley rode across Hounslow Heath lace one night, singing a favorite hymn, he was startled by a fierce voice shouting, "Halt," while a firm hand seized the horse's bridle. Then the man demanded, "Your money or your life."
Wesley obediently emptied his pockets of the few coins they contained and invited the robber to examine his saddlebags which were filled with books. Disappointed at the result, the robber was turning away when evangelist cried, "Stop! I have something more to give you."
The robber, wondering at this strange call, turned back. Then Wesley, bending down toward him, said in solemn tones, "My friend, you may live to regret this sore of a life in which you are engaged. If you ever do, I beseech you to remember this, 'The blood of Jesus Christ, God's Son, cleanses us from all sin."' The robber hurried silently away, and the man of God rode along, praying in his heart that the word spoken might be fixed in the robber's conscience.
Years later, at the close of a Sunday evening service with the people streaming from the large building, many lingered around the doors to see the aged preacher, John Wesley.
A stranger stepped forward and earnestly begged to speak with Mr. Wesley. What a surprise to find that this was the robber of Hounslow Heath, now a well-to-do tradesman in the city, but better still, a child of God! The words spoken that night long ago had been used of God in his conversion.
Raising the hand of John Wesley to his lips, he affectionately kissed it and said in tones of deep emotion, "To you, dear sir, I owe it all."
Wesley replied softly, "Nay, nay, my friend, nor to me, but to the precious blood of Christ which cleanseth us from all sin."
