The wise and the foolish differ not in nature, only in conduct.
The wise man is he who Does the Words of the Lord,
While the foolish man is he who Does NOT Obey Them.
The Rock stands for the Words of the Lord,
But the sand signifies the ideas of man.
To Build Upon the Rock is to do EVERYTHING According to God’s Word;
To build upon the sand is to do things according to one’s own ideas.
