Quotes about Impregnable

The mind, unconquered by violent passions, is a citadel, for a man has no fortress more impregnable in which to find refuge and remain safe forever.

And therefore let thy chief fort and place of defence be, a mind free from passions. A stronger place, (whereunto to make his refuge, and so to become impregnable) and better fortified than this, hath no man. He that seeth not this is unlearned. He that seeth it, and betaketh not himself to this place of refuge, is unhappy.

The soul that is yielded to Christ becomes His own fortress, which He holds in a revolted world, and He intends that no authority shall be known in it except His own. A soul thus kept in possession by the heavenly agencies is impregnable to the assaults of Satan.
