Let the Peace of Christ Rule in Your Hearts—Colossians 3:15
“Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful” (Colossians 3:15)
My husband is a huge baseball fan. To be more specific, he’s an enormous fan of the St. Louis Cardinals. This means many of our summer hours are filled with watching games, checking scores on his phone, and even driving to St. Louis to sit in the stands and root for his team.
Now, I am not a baseball fan, but one position in the game has always captured my interest: the umpire. In a world of high-tech instant replays and slow-motion analysis, the umpire's role remains remarkably significant. This person makes the calls during the game. Their decision is based on what they see, their deep knowledge of the rules, and most importantly, their call is final. It is not up for negotiation or second-guessing once it has been made. The umpire is the final authority.
In our own lives, as 'God’s chosen people, holy and dearly loved,' we also have an umpire to act as the final authority. That referee is the peace of Christ. This is the beautiful instruction Paul gives in Colossians 3:15: “Let the peace of Christ rule in your hearts, since as members of one body you were called to peace. And be thankful.”
The Umpire in Your Heart
What does it mean to let peace "rule" in our hearts? The original Greek word for "rule" here is fascinating. It carries the idea of an umpire or a referee who presides over a contest and decides the outcome. The Amplified Bible captures this beautifully: “And let the peace (soul harmony which comes) from Christ rule (act as umpire continually) in your hearts [deciding and settling with finality all questions that arise in your minds, in that peaceful state] to which as [members of Christ’s] one body you were also called [to live]. And be thankful (appreciative), [giving praise to God always].”
Think about the questions and conflicts that arise in your mind daily. Should I take this job? How should I respond to that hurtful comment? Is this worry worth the energy I’m giving it? Our hearts can feel like a chaotic field of play with conflicting emotions, anxieties, and desires all vying for control.
In the midst of this internal chaos, Paul tells us to let the peace of Christ be the umpire. This peace is not a fleeting feeling or the absence of conflict. It is a deep, soul-level harmony that comes directly from Christ. It has the authority to step in, make the final call, and settle the questions that trouble our minds. When we are faced with a decision and one path brings a sense of deep, settled peace while the other brings turmoil, we are to let that peace have the final say. It’s a spiritual gut-check, a signal that we are aligned with the heart of God.
A Peace That Overcomes the World
Living in a state of peace can feel like an impossible calling. The world is full of turmoil, trouble, and uncertainty. Yet, this is precisely why Jesus offered us His peace. He knew the world we would be living in. He said, “I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world” (John 16:33).
The peace of Christ is not dependent on our circumstances. It is a gift given to us because He has already overcome the world. It is a peace rooted in the truth of who He is and what He has done. When we feel the chaos of the world pressing in, we can consciously choose to rest in the truth of the gospel—that we are forgiven, we are loved, and our future is secure. This truth is the foundation that allows peace to act as the umpire in our hearts, settling us into a place of rest even when storms rage around us.
This peace is also a gift God strengthens His people with. The psalmist declared, “The Lord gives strength to his people; the Lord blesses his people with peace” (Psalm 29:11). It is both a blessing we receive and a state we are called to live in.
The Role of Thankfulness
It is no accident that Paul ends this verse with a simple but profound command: “And be thankful.” Thankfulness is deeply connected to peace. An ungrateful heart is often a restless one, always looking for what it lacks. A thankful heart, however, is one that is focused on the goodness of God.
When we practice gratitude, we shift our focus from our problems to our Provider. We remember His faithfulness, we acknowledge His blessings, and we affirm His presence in our lives. This posture of thankfulness creates fertile ground for the peace of Christ to rule. It quiets the anxious voices and allows the umpire’s call to be heard clearly. Peace and thankfulness work together, creating a cycle of rest and contentment in the believer’s heart.
Today, what decisions are you facing? What anxieties are competing for your attention? Instead of letting them run rampant, invite the peace of Christ to be the umpire. Take a moment to quiet your heart, present your questions to Him, and listen for that soul-harmony that settles your spirit. Let His peace make the final call. And as you do, remember to be thankful, acknowledging the Giver of all peace and rest.
