Hearing and obeying Jesus is the stable foundation of discipleship.

Matthew 7:24–27

²⁴Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:

²⁵And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.

²⁶And 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:

²⁷And 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.
