House built on the rock
Builder is wise
Rains floods winds will not knock the house down.
It will not fall in the beatings.
It is founded on the rock.
House built on the sand
Rains floods and winds come and beat in the house
The house falls
The fall is great
Built on the rock: listens to the words Jesus says, and does them.
Built on the sand: hears but does not do them.
Build on the rock of Jesus. Listen to His words. Obey them.
When things get hard He will keep us grounded to Him.
