During this unprecedented season of social distancing, with only nine people gathered in the sanctuary, Pastor Josh White delivered a powerful message on the nature of true Christian unity—using an unforgettable analogy about metal shavings and marbles.
The Context: A Church Scattered
The church building was nearly empty. Announcements were simple: everything was canceled, everything was postponed. This was the new reality of March 2020, and it prompted deep reflection on what the church actually is—and what holds it together.
Paul’s letter to the Philippians addresses a church facing its own tensions, and now, thousands of years later, his words cut through our present circumstances with striking relevance. Paul opens Philippians chapter 2 with four appeals that form the foundation for unity:
If there is any encouragement in Christ, any comfort from love, any participation in the Spirit, any affection and sympathy, complete my joy by being of the same mind, having the same love, being in full accord and of one mind.
Paul identifies three things that should mark Christ’s followers: encouragement, comfort, and participation—each drawing us deeper into relationship with God and with one another. But here’s the key: unity is not something forced from the outside. It must be internally desired.
The Metal and Marble Analogy
Borrowing an illustration from John MacArthur, Pastor Josh presented a vivid picture of what true unity looks like—and what it doesn’t.
Imagine a bag of marbles. Hundreds of little glass balls, all packed together in perfect unity. But why are they together? Something external is forcing them—the bag itself. The moment you cut the bag open, they scatter in every direction. That forced unity dissolves the instant the external pressure is removed.
Now consider metal shavings spread across a table. They’re completely scattered, no unity at all. But bring a powerful magnet overhead, and watch what happens. Immediately, they rush together—not because something is forcing them, but because of what they are. They are metal. The magnet draws them to itself and to each other.
The magnet is Jesus. When we are truly in Christ, we are drawn to Him, and that drawing creates genuine unity with other believers. This unity is not manufactured by programs, policies, or peer pressure. It flows from an internal transformation.
Philippians 2:4 — The Heart of the Matter
Paul drives the point home in Philippians 2:4:
“Let each of you not only look to his own interests, but also to the interests of others.”
This is the mark of metal, not marble. The person who is only present because of external compulsion—routine, family obligation, social expectation—will scatter when trials come. But the person whose heart has been changed by the Spirit, who genuinely desires Christ and His body, will be drawn to others even in difficult circumstances.
The Question for Today’s Church
As churches were forced to stop gathering in March 2020, an important question emerged: When this is over, what will the church look like?
How many people were only present because they had been externally compelled? How many would drift away the moment the “bag” was removed? The COVID crisis was, in a strange way, a test of whether a person’s unity with the body of Christ was genuine or merely circumstantial.
Are you metal, or are you marble? Do you come to church because something is forcing you—your schedule, your family, your reputation? Or do you come because something inside you is magnetically drawn to Christ and to His people?
The good news is this: if you are in Christ, you have the nature of metal. The Holy Spirit has placed that magnet of God’s love in your heart. The question is not whether you can have genuine unity—it’s whether you will yield to the pull.
Application
As you navigate this unique season, consider:
- Examine your heart. Is your participation in church life driven by external obligation or internal desire?
- Embrace the magnet. Draw near to Christ, and let Him draw you near to others.
- Look outward. Philippians 2:4 calls us to look not only to our own interests, but to the interests of others—especially in times of crisis.
- Trust God’s preservation. The body of Christ will experience change, but God is faithful to complete His work.
When the bag is cut open and everything is scattered, let the magnet of God’s love pull you back—not just to a building, but to His people. Be metal, not marble.
