Brother Christian, you carry much combustible matter in your nature, be warned when you see your neighbour’s house on fire. When one man falls, the next should look to his steps. You are a man of like passions, remember yourself, lest you also be tempted. In these days of epidemics, if we knew that a certain house was tainted with disease, and if we saw a person who had come from it with the marks of the disease in his face; what should we feel? Should we not take it as a warning to keep clear, both of the house and of him; because we ourselves are as likely to take the disease as He was? So when we see a sinner transgressing we should say to ourselves, “I also am a man, and a fallen man, let me abhor every evil way, and guard myself jealously, lest I also fall into sin.”
