We end our series on the Sermon on the Mount with the Matthean passage that ends the sermon in chapter 7. It is the familiar story of two houses, one built on sand and the other on rock. It is easy to understand the difference, but what does it mean for Jesus to caution us to build our house on rock? And how, in our current situation of needing to keep our distance from others during the COVID-19 threat, do we hear the words and act on them?
