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:
27 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.
So in verse 24 and 25 Jesus is saying that if you build your house (life) upon a rock (the bible) when hard times come you will be able to withstand them because of you're strengthened relationship with Jesus through the bible. Now in verse 26 and 27 Jesus is saying the exact opposite. If you build your house (life) on the sand (the world or worldly possessions) then when hard times come you're going to come apart. Make sure there is nothing in you're life that comes before God. Because God wants to have a relationship with you and if you're distracted that relationship is going to unravel.
