It doesn’t end well for the person who builds on lawlessness. Thus, Jesus compares lawlessness to sand. Sand is far from a suitable material to build anything on. So we can imagine that if someone built a house on sand, how the house would fall. This fall might not be apparent immediately. But the more one builds on such a weak foundation, the greater that fall will be. This is the point Jesus makes when he describes the builder who builds on sand. Jesus says, “and the rain descended, the floods came, and the winds blew and beat on that house; and it fell. And great was its fall” (Matthew 7:27). Jesus stresses that the fall of the house built on sand is not only approaching but great.
