That which is built on sand is crumbling.

Those things built on sand are crumbling.

Everyone who listens to these words of mine but does not act on them will be like a fool who built his house on sand. The rain fell, the floods came, and the winds blew and buffeted the house. And it collapsed and was completely ruined. (Matthew 7:26-27)


But that which is built on the rock of Peter is standing. For Christ promised that the gates of hell would not prevail against the Church which He himself would build.
