Dr. Arnot was accustomed to tell a story of a poor woman who was in great distress because she could not pay her landlord his rent. The doctor put some money in his pocket, and went round to her house, intending to help her. When he got there he knocked at the door. He thought he heard some movement inside; but no one came to open the door. He knocked louder and louder still; but yet no one came. Finally he kicked at the door, causing some of the neighbours to look out and see what was going on, but he could get no entrance. At last he went away, thinking his ears must have deceived him, and that there was really no one there. A day or two afterward he met the woman in the street, and told her what had happened. She held up her hands and exclaimed—"Was that you? I was in the house all the while; but I thought it was the landlord, and I kept the door locked!" Many people think the grace of God is coming to smite them. My dear friends, it is coming to pay all your debts! D. L. Moody (Anecdotes, Incidents and Illustrations)
