The Sermon on the Mount Pt. 2 – Lesson 14: Build Your House

“Therefore whosoever heareth these sayings of mine, and doeth them, I wilt liken him unto a wise man, which built his house upon a rock. And 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.” —Matthew 7:24, 26

Scripture Reading: 2 Peter 1:3-10; 2 Corinthians 3:10-15


Whether or not we know God is evidenced by the fruit in our lives. Good fruit only comes from a good tree and the only good tree is one transformed by the life of Jesus. It is with this in mind that Jesus speaks of the wise and foolish men building their houses. We must choose to build on the Rock of Jesus Christ or on the sand of our own desires and wants. What we build upon is evidenced by one thing—our obedience to Christ’s commands. Matthew 7:21-23 tells us we must know Christ, or our works are worthless. But the evidence of truly knowing Christ is doing what He said, or put in another way, building our house on the Rock.

No one who knows anything about construction would use sand for the foundation of a house. The reason is obvious—sand isn’t stable and it moves as the environment shifts. On the other hand, rock stands firm in the face of a changing environment. Contractors know this and build houses on the rock we call concrete. if a contractor built a house on the sand, he might be met with emphatic responses like, “Are you crazy?” or “Your house won’t last long!” or “You’re simply wasting your money!”

Do we respond to our own actions in the same way? Would we say to ourselves, “Your house won’t last long if you continue that sinful habit?” It’s so easy to see the folly actually building a house on the sand. Yet, Christ is calling us to see the folly in building our lives on the sand. The evidence of a sandy foundation in construction is just as easy to see as the evidence of a sandy foundation in our lives. The question is: “Will we tear down our house, forsake the sand, and go build on the Rock?”

Life Application:

This week, choose two areas of your life you know the Word says you should change. Then, determine to do three things differently for both problem areas. For instance, if you struggle with envy, give something away that you treasure. Or, if you struggle with pride, give your support to others’ ideas and opinions for an entire week.
