The Blessing of Unity Among Brothers
A beautiful and powerful truth found in Psalm 133: the blessing of unity among brothers. This psalm paints a vivid picture of the joy and power that come from harmonious fellowship. One of the most poorly understood words in the entire Christian church is the word union (or unity). We gather frequently inside our church buildings, we crowd into pews, but so often there is no genuine sharing of life.
Sermon: The Blessing of Unity Among Brothers
Introduction: The Misunderstood Mirror of Community
The local church must be an intentional environment where every single Christian feels deeply valued and experiences authentic, tangible love directed toward them, simply because they are a blood-bought member of the family of God. Perhaps the most essential and vital manifestation of church life happens when we gather intimately, yet this mutual intimacy with one another and with the Lord is exactly what is missing in the lives of many churches today.
God's blueprint for community is not silent on how we must interact. In fact, within the context of local church life, the phrase "one another" or "each other" appears approximately 64 times, almost always delivered as an urgent, commanding imperative. The overarching message of these reciprocal commandments is clear: I am strictly called to love and serve my brothers and sisters.
Let us open our hearts to Psalm 133 to discover why unity is non-negotiable, how it acts as a magnet for God's presence, and the practical steps we must take to preserve it.
Part I: The Beautiful Nature of Corporate Unity
1. Unity Among Brothers Is Precious
The psalmist begins with an urgent exclamation of wonder and pure delight:
"Behold, how good and how pleasant it is when brothers dwell together in unity!" — Psalm 133:1
This text highlights just how uniquely precious true unity is. It is not merely "good" in a structural sense; it is also profoundly "pleasant." It is a sovereign gift from Almighty God, a beautiful treasure that the local church must actively cherish. When we experience true, unhindered unity in the body of Christ, we are experiencing a physical taste of heaven right here on earth.
2. Unity Produces Harmony and Peace
By repeating the words "how good and how pleasant," the Holy Spirit emphasizes the absolute sweetness of Christian fellowship. Living in dynamic unity brings deep, foundational harmony and peace.
• Where there is division, there will always be bitter strife.
• But where there is true unity, a sweet, gentle, and quiet spirit completely permeates the community, making it attractive to the broken.
Part II: The Dynamic Flow of the Spirit and Blessing
3. Communion Is Like Precious Oil
The text shifts to a powerful, fragrant illustration:
"It is like the precious oil on the head, running down on the beard, the beard of Aaron..." — Psalm 133:2
The Psalmist uses the image of precious anointing oil, which directly symbolizes God's anointing and His holy presence. Just as that sacred oil flowed freely and unstoppably, so does God's Spirit flow without restriction in a community that is marked by unity. True, biblical communion is always explicitly authenticated by the active presence of the Holy Spirit.
4. An Expression of the Spiritual Priesthood
The oil did not just fall anywhere; it ran down the beard of Aaron. Aaron, as the high priest, represents our collective spiritual priesthood today. A unified church operates in its priestly calling, standing before the world as a living, breathing testimony to God's ultimate power and transforming grace.
5. God’s Blessing Flows from Top to Bottom
The description continues:
"...running down on the hem of his garments." — Psalm 133:2
This paints a vivid picture of how God's divine blessing flows logically from the head all the way down to the rest of the body. When a church maintains unity, God's grace pours out globally upon everyone, touching every hidden aspect of our lives from the highest leader to the newest believer.
6. Unity Brings Renewal and Life
The setting then shifts from the tabernacle to the mountains:
"It is like the dew of Hermon..." — Psalm 133:3
Unity is directly compared to the refreshing dew of Mount Hermon, which naturally cools, refreshes, and completely renews the parched earth. True fellowship revitalizes our faltering faith and strengthens us when we are weary. Just as dew brings life back to dry soil, christian unity brings deep spiritual refreshment to dry souls.
7. A Shower of Blessings
This dew is described as:
"...that descends upon the mountains of Zion." — Psalm 133:3
Just as physical dew waters the ground to bring forth fruit, intentional fellowship practically strengthens the church. When we choose to gather in true unity, God sends supernatural spiritual growth and abundance across our ministries.
8. The Commanded Blessing
Pay close attention to this unshakeable spiritual law:
"For there the Lord commanded the blessing..." — Psalm 133:3
The Word declares that God commands His blessing to rest specifically where there is unity! Conversely, corporate disunity and internal gossip completely block the flow of God's blessings. When we are unified, we create the necessary spiritual space for God to pour out His unhindered grace.
9. Eternal Life Is the Greatest Fruit
The psalm concludes with the ultimate fruit of unity:
"...And life forevermore." — Psalm 133:3
True fellowship among the saints is a prophetic foreshadowing of our eternal communion with God in heaven. Our unity in faith right now is preparing us to live with Him forever in glory.
10. Our High Calling to the Watching World
Because of this, the church is strictly called to reflect this unity globally (Psalm 133:1). Our love and harmony must serve as a powerful, undeniable witness to a fractured world. When we live in real harmony, we display the raw glory of God and testify to the transforming power of the Gospel of Jesus Christ.
Part III: The Practical Execution – How to Love My Brother
How do we practically build this environment of unity? The New Testament "one another" mandates give us clear, actionable instructions on how to love our brothers and sisters:
• Practice Holy Greeting: "Greet one another with a holy kiss." (Romans 16:16). We must welcome each other intentionally.
• Be Unconditionally Hospitable: "Be hospitable to one another without grumbling." (1 Peter 4:9).
• Receive Each Other Completely: "Receive one another, just as Christ also received us, to the glory of God." (Romans 15:7).
• Prefer Others in Honor: "Be kindly affectionate to one another with brotherly love, in honor giving preference to one another." (Romans 12:10).
• Walk in True Humility: "...in lowliness of mind let each esteem others better than himself." (Philippians 2:3).
• Maintain Peace: "...and have peace with one another." (Mark 9:50).
• Be Kind and Compassionate: "And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you." (Ephesians 4:32).
• Cooperate with Equal Care: "...that the members should have the same care for one another." (1 Corinthians 12:25).
• Live in Harmony of Mind: "Be of the same mind toward one another." (Romans 12:16).
• Intercede Continuously: "...and pray for one another, that you may be healed." (James 5:16).
• Instruct and Advise Mutually: Teach and admonish one another in all wisdom with psalms, hymns, and spiritual songs (Ephesians 5:19; Colossians 3:16).
• Serve Practically: "As each one has received a gift, minister it to one another..." (1 Peter 4:10).
• Walk in Lowly Service: Jesus modeled this directly: "If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet." (John 13:14).

Conclusion: The Ultimate Growth of the Body
As we look at the immense weight of these scriptures, let us understand where this all leads. True unity is not about hiding our differences or pretending we are all identical; it is about growing up together into our Head. Let us read and anchor our souls to the reality found in Ephesians 4:15-16:
"...but, speaking the truth in love, may grow up in all things into Him who is the head—Christ—from whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love."
Church, look at the text! The growth of the body only happens when every joint supplies its share, and when we speak the truth in love. When we choose to drop gossip, stop judging, bear each other's burdens, and share our lives in small groups and corporate worship, we become the very place where God commands His eternal blessing.
Let us commit tonight to being true caretakers of unity. Let the oil flow, let the dew fall, and let the name of Jesus Christ be glorified through our unshakeable love for one another!
Amen.
