EVERY individual is a mental householder and need entertain only the thoughts of his own selecting. He is his own doorkeeper, and, like an alert sentry, should always be ready with the challenge, "Who goes there?" One who remains awake at his post will not fall into wrong mental company.
Christ, Truth, is the criterion as to the origin and veracity of every thought. Many random suggestions may presage evil, failure, sickness, but these are fraudulent mischief-makers; they lack the hall mark of Truth. Theoretically, every student of Christian Science knows how to distinguish between a true thought and a false belief; but the question is, Does he always apply this precious knowledge, which is his passport to heaven?
Correctness of argument must be accompanied by a right spirit, according to Mrs. Eddy's statement in "Science and Health with Key to the Scriptures" (p. 418), "By the truthful arguments you employ, and especially by the spirit of Truth and Love which you entertain, you will heal the sick." Divine Truth and Love are all-inclusive: they exclude error. They have no real rivals, and must have no spurious rivals in our thinking. If we regard every situation, however difficult or aggressive, in a healing spirit, and admit only such thoughts as God entertains for His image and His universe, our rebuke to error will be sharp, specific, conclusive and our victory certain.
