Toward the end of His soul-stirring Sermon on the Mount (Matthew 5-7), Jesus told an intriguing yet practical parable about two men, each of whom set out to construct a house. According to the specific details provided by the Lord, one man-whom He referred to as "foolish"-decided to build his house upon a foundation of shifting sand; the other-whom Christ called "wise"-decided to build his house upon a foundation of solid rock.
