Suppose we were to have one hundred concert pianos, all needing to be in tune to one another. If you tune the second piano to the first, and the third piano to the second, and the fourth piano to the third, and so on, until you have tuned all one hundred pianos accordingly, you will still have discord and disharmony. But if you tuned each piano to the same tuning fork, there would be a different result. Then you would have perfect unity and harmony among all the pianos. So it is in the body of Christ. When believers try to tune themselves to one another, it results in disharmony. But when each saint brings himself into one accord with Jesus Christ, glorious unity results in the body of Christ. Psalm 133 is a song about unity among God’s people, who are in tune with the character of God.
