Don’t Rebuild Walls Christ Tore Down

Psalm 133:3

In this lab, John Piper shows us that Christ’s blood is the great adhesive that unites the church together across time, racial divides, and class distinctions.

Some questions to ask as you read and study Psalm 133:3:

  1. Have you found unity and fellowship with other Christians to be life-giving? Do you have such life-giving fellowship in this season of life?
  2. How does the ground in verse Psalm 133:3 (“For there the Lord has commanded the blessing, life forevermore”) support what came before it? For more on what a “ground” is, see Principle for Bible Reading below.
  3. How did Jesus create unity among his people (Ephesians 2:13–18)? Are you working for or against that unity in your local context?

Principle for Bible Reading


A “ground” is an argument or reason for another statement. One way to remember this is that the ground is the ground upon which another statement is built. The supporting (or grounding) statement comes after the statement it supports. When you come to a grounding statement in the Bible, ask what came before it that it supports.
