We must beware of false reasoning, such as: because our fire does not blaze up as others, we therefore have no fire at all. By false conclusions we might break the commandment by bearing false witness against ourselves. The prodigal would not say that he was not a son, but that he was not worthy of being called a son (Luke 15:19). We must neither trust false evidence nor deny true evidence, for by doing so we would dishonor the work of God's Spirit in us.
