And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand: And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it. (Matthew 7:26, 27 KJV)

How to be saved.
How to be born again.
How to obtain eternal life.
