Just imagine building your house directly on the sand with no foundation. Of course, we know that the sand will shift with the wind and currents so eventually that house will collapse. Our lives are the same way. When we build our lives on the shifting sand of worldly pursuits, eventually our lives will collapse. On the other hand, Jesus never changes and never shifts with changing conditions so it is best to build our lives on the eternal and never-changing Jesus Christ. It’s on Jesus alone that we find a foundation that will last forever.
