This sermon appears to call the church to become a people of wisdom by building life on Jesus as the true cornerstone. In Matthew 7:15-29, the message likely brings together discernment about false voices, the call to do the Father's will, and the contrast between houses built on rock and sand. The opening meditation on the cornerstone gives the sermon a strong architectural image: when Jesus sets the line and measure of life, his people become unshakable. The hope in the message is that wisdom is not reserved for the especially gifted. It is available to all who hear the words of Jesus and actually build on them, finding stability in him through every storm.
