In construction, a solid foundation is key to building a sound structure. The well established practice of digging down to bedrock to place the foundation is as reliable today as in ancient times. This is because in order for a structure to be stable, it has to be secured to something stable. Even though the ground for a building site may seem suitable for construction at first, if it’s not solid rock, it will change when conditions change: in the presence of storm and flood waters, sand will erode, clay will swell and heave. If it is made from inadequate materials or not properly reinforced, the foundation itself will be the weak link.
And no matter how strong the foundation is, a structure that isn’t properly connected to it won’t benefit from that strength when faced with an earthquake or hurricane that can knock it right off its base. The bottom line is, any structure will fail if it’s not securely connected to a foundation that’s constructed to resist the forces that will act against it.
Jesus used this fact about foundations when He said,
I will show you what it's like when someone comes to me, listens to my teaching, and then follows it. It is like a person building a house who digs deep and lays the foundation on solid rock. When the floodwaters rise and break against that house, it stands firm because it is well built. But anyone who hears and doesn't obey is like a person who builds a house without a foundation. When the floods sweep down against that house, it will collapse into a heap of ruins." (Luke 6:47-49 NLT)
In His example, Jesus makes it clear that He is the Foundation, and the only Rock that is suitable to build on.
It says, “Jesus Christ, the same… yesterday, today, and forever.” So, He’s always going to be the same, and He doesn’t change. (excerpt from Fellowshipping With the Holy Spirit, by Dr. Chester C. Pipkin, Jr.).
He is a solid Foundation that will never change, no matter what the circumstances are around us. And the way for us to build upon Jesus as our Foundation is by seeking Him and His teaching, and then doing it! All the latest social theories, voices in the chat rooms, and experts on the news are subject to change with the times and seasons. Whether or not they are valid, they are never suitable as our foundation. Only Jesus and His teachings (that is, the Bible) will remain firm and unchanging. Therefore, like skilled builders, we must build our lives on Christ, the Rock of Ages, and be securely anchored to Him, the only One who enables us to endure through every storm and trial and not collapse into a heap of ruins.
