that they may be made perfect in one.”
When a symphony performs, each musician has something different to contribute. The title of each piece of music is the same, but there are many different parts that make up that one piece. A musician may be an extremely talented soloist, but playing in harmony with others requires a great deal of practice, preparation and group rehearsal. It also requires each musician to submit to the direction of the conductor. If that means playing “second fiddle” then so be it. Working together takes time and patience – two things that most people do not have an abundance of.
I trust you can see that even in this simple illustration, pride, egotism, and an unwillingness to work with others disqualifies even the greatest musicians from becoming viable members of a symphony. Christ, the Master Conductor, seeks a spiritual harmony among all His disciples: “that they all may be one… that they also may be one in Us” (John 17:21).
