So you also outwardly indeed appear to men just; but inwardly you are full of hypocrisy and iniquity. (Matthew 23:28)

What greater hypocrisy can there be, than to claim to be a person of the spirit, but to recognize only material reality? Such people, if they inwardly affirm God at all and not merely as public performance, believe in him only as an abstraction from physical things, and bend all of their thoughts to the cares of this world. This spiritual decay leads only to death.
