Logion 31

31. Jesus said, “No prophet is welcome in his own village; no physician worketh a cure on those that know him.”
Mk 6:4: And Jesus said unto them, “A prophet is not without honour, but in his own country, and among his own kin, and in his own house.”
Lk 4:24: And he said, “Verily I say unto you, ‘No prophet is accepted in his own country.’”

The effectiveness of a cure wrought by faith resides in the soundness of that faith. The patient cannot doubt the power of his savior. When we are familiar with a person, we know his frailties and human nature. But when the prophet speaks for God, or the physician prescribes a cure, he must be anonymous as an agent of an unseen power. Otherwise our consciousness overrides the deeper knowledge that he advises beyond our own experience.
