Read Matthew 7:24-29 to start.

The wise man built his house upon the rock. That’s of course the title of a children’s song we sing from time to time, it’s not one we trot out every single week or anything, but I recall it being quite popular when I was Sunday School age. The first two verses of that song are lifted wholesale from this passage of scripture. Those two verses tell the story of prudent construction versus unwise building methods, much as the parable we read to start does. It’s a familiar account, and a familiar song, and it’s an easy to understand principle as it applies both to building a house and to establishing your manner of living. If you follow Christ, if you hear His words and decide to obey them, then you will be established and sound. If you do not, then you will find yourself, as Paul describes in Ephesians chapter four, tossed about by every wind of doctrine. The wise man takes one approach, the foolish man a different one, and the results speak for themselves.
