This small group deep study guide draws directly from Jeremy Wood's sermon “United for mission” so you can keep engaging with the message all week. Read, reflect, and share it with your small group or friends.

UNITED FOR MISSION: UNITY AS THE PLATFORM FOR GOD'S POWER

Small Group Deep Study Guide

INTRODUCTION TO THIS STUDY

This comprehensive study guide has been designed to help your small group explore the theological depth and practical implications of unity as the foundation for God's power working through the church. Based on the sermon "Unity Is the Platform for God's Power," this guide will take you deeper into the biblical texts, historical context, and theological concepts presented in the message.

OPENING PRAYER

Before beginning your study, take time to pray together, asking God to open your hearts and minds to His Word and to help you apply what you learn.

Heavenly Father, as we gather to study Your Word more deeply, we ask that Your Holy Spirit would guide our discussion and illuminate the truths of Scripture. Help us not just to understand intellectually but to be transformed by what we learn. May our study of unity lead us to greater oneness in Christ and effectiveness in mission. In Jesus' name, Amen.

SCRIPTURE FOUNDATION

Primary Text: Psalm 133 Supporting Texts: Ephesians 4:1-16; Acts 2:42-47; John 17:20-26

Take time to read these passages aloud in different translations before beginning your discussion.

PART 1: UNITY AS A SPIRITUAL REALITY

DEEP DIVE INTO PSALM 133

Text Analysis: Read Psalm 133 carefully, noting its structure and imagery:

"How good and pleasant it is when God's people live together in unity! It is like precious oil poured on the head, running down on the beard, running down on Aaron's beard, down on the collar of his robe. It is as if the dew of Hermon were falling on Mount Zion. For there the LORD bestows his blessing, even life forevermore." (Psalm 133:1-3, NIV)

Historical and Cultural Context:

This psalm is attributed to David and is classified as a "Song of Ascents" (pilgrimage psalm sung by worshippers traveling to Jerusalem for festivals).
The imagery of oil refers to the anointing of Aaron as high priest (Exodus 29:7, Leviticus 8:12). This was not ordinary oil but specially prepared sacred anointing oil (Exodus 30:22-33).
Mount Hermon, the tallest mountain in the region (over 9,000 feet), was known for heavy dew formation. Mount Zion (Jerusalem) was much drier. The image suggests something from one place bringing life to another.

Theological Insights:

The psalm presents unity not merely as a pleasant social reality but as a sacred, divinely ordained condition.
The connection between unity and blessing is explicit: "For there the LORD bestows his blessing."
The ultimate blessing is "life forevermore" - suggesting unity has eternal implications.

Cross-References:

John 17:20-23 - Jesus prays for the unity of believers as a testimony to the world
1 Corinthians 12:12-27 - The church as one body with many parts
Ephesians 4:1-6 - The theological basis for Christian unity

EPHESIANS 4:3-6 EXEGESIS

"Make every effort to keep the unity of the Spirit through the bond of peace. There is one body and one Spirit, just as you were called to one hope when you were called; one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all."

Key Greek Terms:

"Keep" (τηρεῖν/tērein) - to guard, maintain, preserve something already existing
"Unity" (ἑνότητα/henotēta) - oneness, unanimity, agreement
"Bond of peace" (συνδέσμῳ τῆς εἰρήνης/syndesmō tēs eirēnēs) - peace as the binding agent that holds unity together

Theological Insight: Paul doesn't instruct believers to create unity but to maintain what the Spirit has already established. Unity is not primarily a human achievement but a divine gift to be preserved.

DISCUSSION QUESTIONS

Theological Reflection: How does understanding unity as a spiritual reality already established by God change your perspective on church relationships?
Textual Analysis: In Psalm 133, what is the significance of comparing unity to both anointing oil and dew? What different aspects of unity might these two images convey?
Deeper Application: The sermon mentioned that "unity is a spiritual reality before it's a practical experience." What is the difference between positional unity (our standing in Christ) and experiential unity (our daily practice)? Where do you see this distinction in Scripture?
Critical Thinking: If unity already exists spiritually among all true believers, why do we experience so much division in the church? What factors contribute to the gap between our spiritual reality and our lived experience?
Personal Reflection: In what ways have you been acting as though unity is something we create rather than something we preserve? How might this misconception affect your relationships with other believers?

THEOLOGICAL REFLECTION: THE TRINITARIAN BASIS OF UNITY

The unity of believers is grounded in and reflects the unity of the Trinity. God exists eternally as three Persons in perfect unity—Father, Son, and Holy Spirit. Our unity as believers is not merely a pragmatic arrangement but a reflection of God's own nature.

Scripture Connections:

John 17:21-23 - Jesus prays that believers would be one "just as you, Father, are in me and I am in you"
1 Corinthians 12:4-6 - The unity and diversity within the Trinity reflected in the church
2 Corinthians 13:14 - The Trinitarian blessing

For Deeper Study: Augustine's concept of the Trinity as a communion of love provides a theological foundation for understanding church unity as participation in divine life rather than merely human cooperation.

PART 2: PROTECTING UNITY

EPHESIANS 4:29-32 EXEGESIS

"Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen. And do not grieve the Holy Spirit of God, with whom you were sealed for the day of redemption. Get rid of all bitterness, rage and anger, brawling and slander, along with every form of malice. Be kind and compassionate to one another, forgiving each other, just as in Christ God forgave you."

Key Terms and Concepts:

"Unwholesome talk" (λόγος σαπρὸς/logos sapros) - literally "rotten or putrid words"; speech that tears down rather than builds up
"Grieve" (λυπεῖτε/lupeite) - to cause sorrow or pain; suggests the Holy Spirit is personally affected by our treatment of one another
"Sealed" (ἐσφραγίσθητε/esphragisthēte) - marked with a seal of ownership and authenticity; a guarantee

Theological Insight: Paul connects our speech and attitudes toward others directly to our relationship with the Holy Spirit. Disunity doesn't just damage human relationships; it grieves God Himself.

MATTHEW 18:15-20 - CHRIST'S PATTERN FOR CONFLICT RESOLUTION

"If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. But if they will not listen, take one or two others along, so that 'every matter may be established by the testimony of two or three witnesses.' If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector..."

Process Analysis:

Private conversation (v.15)
Small group mediation (v.16)
Church involvement (v.17)
Potential separation as last resort (v.17b)

Contextual Insight: Jesus provides this pattern immediately after telling the parable of the lost sheep, emphasizing that the goal is restoration, not punishment or exclusion.

DISCUSSION QUESTIONS

Exegetical Question: In Ephesians 4:30, Paul says disunity "grieves" the Holy Spirit. What does this tell us about God's emotional investment in our unity? How does this affect your view of church conflicts?
Theological Reflection: The sermon identified three practical commitments for protecting unity: refusing to gossip, extending quick forgiveness, and focusing on essentials. For each of these, identify the theological principle behind it and additional Scripture passages that support it.
Case Study: Consider a situation where a church member is upset about a decision made by leadership. Using Matthew 18:15-20 as a guide, outline the biblically appropriate steps they should take. What common responses violate this pattern?
Historical Perspective: Throughout church history, Christians have debated which doctrines are "essential" versus "non-essential." Research and discuss the concept of "In essentials unity, in non-essentials liberty, in all things charity." How might this principle guide unity discussions?
Application Depth: Forgiveness is commanded, but reconciliation often requires more than a one-time decision. Discuss the relationship between forgiveness (a decision) and reconciliation (a process). How does understanding this distinction help protect unity?

THEOLOGICAL REFLECTION: UNITY AND CHURCH DISCIPLINE

Scripture presents both the imperative to maintain unity and the necessity of church discipline. These are not contradictory but complementary. True biblical unity is not unity at any cost or unity without truth.

Scripture Connections:

1 Corinthians 5:1-13 - Paul instructs the church to remove an unrepentant member
Galatians 2:11-14 - Paul confronts Peter publicly when his actions threatened gospel unity
2 Thessalonians 3:6, 14-15 - Instructions to withdraw from those who are disorderly, yet still regard them as brothers

For Deeper Study: Dietrich Bonhoeffer's distinction between "cheap grace" and "costly grace" in his book "The Cost of Discipleship" provides insight into how genuine unity requires truth and accountability, not merely tolerance of sin.

PART 3: UNITY RELEASES GOD'S POWER FOR MISSION

ACTS 2:42-47 EXEGESIS

"They devoted themselves to the apostles' teaching and to fellowship, to the breaking of bread and to prayer. Everyone was filled with awe at the many wonders and signs performed by the apostles. All the believers were together and had everything in common. They sold property and possessions to give to anyone who had need. Every day they continued to meet together in the temple courts. They broke bread in their homes and ate together with glad and sincere hearts, praising God and enjoying the favor of all the people. And the Lord added to their number daily those who were being saved."

Key Greek Terms:

"Devoted" (προσκαρτεροῦντες/proskarterountes) - to persist in, to be devoted to with intense effort
"Fellowship" (κοινωνίᾳ/koinōnia) - partnership, participation, sharing in common
"Together" (ἐπὶ τὸ αὐτό/epi to auto) - literally "upon the same," emphasizing physical and purposeful togetherness

Historical Context: This passage follows Pentecost, when the Holy Spirit fell on the disciples and 3,000 people were converted. This description shows the immediate fruit of the Spirit's outpouring and the formation of the first Christian community in Jerusalem.

Structural Analysis:

Internal practices of the community (v.42)
Supernatural manifestations (v.43)
Radical generosity and care (vv.44-45)
Ongoing community life (v.46)
External impact and growth (v.47)

JOHN 17:20-23 - JESUS' PRAYER FOR UNITY

"My prayer is not for them alone. I pray also for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. I have given them the glory that you gave me, that they may be one as we are one—I in them and you in me—so that they may be brought to complete unity. Then the world will know that you sent me and have loved them even as you have loved me."

Key Insights:

Jesus prays for all future believers, not just the disciples present
The unity of believers is compared to the unity within the Trinity
The purpose of unity is explicitly missional: "so that the world may believe"
Unity is connected to the glory Jesus imparts to believers

DISCUSSION QUESTIONS

Exegetical Question: In Acts 2:42-47, what is the relationship between the church's unity and the supernatural manifestations described? Does the text suggest a causal connection?
Theological Reflection: Jesus prays in John 17 that believers would be "one as we are one." What does it mean for human relationships to reflect Trinitarian unity? Is this even possible this side of heaven?
Historical Analysis: The sermon referenced the Welsh Revival of 1904-1905. Research this or other revival movements in church history. What role did unity play in these movements? What can we learn from them?
Missiological Question: How does disunity in the church hinder evangelism and mission? Provide specific examples from your experience or observation.
Practical Application: The sermon stated, "We are not united to be comfortable. We are united to be sent." How might this perspective change how your small group functions? What specific mission might God be calling your unified group to pursue?

THEOLOGICAL REFLECTION: UNITY AND REVIVAL

Throughout church history, periods of revival have often been preceded by and characterized by unusual unity among believers. This pattern suggests a theological connection between unity and the outpouring of God's Spirit in power.

Scripture Connections:

Acts 1:14, 2:1 - The disciples were "all together in one place" when Pentecost occurred
Acts 4:31-33 - After praying together "in one accord," the believers were filled with the Spirit and spoke boldly
2 Chronicles 5:13-14 - When the musicians and singers were "as one" in praising God, the glory of the Lord filled the temple

For Deeper Study: Jonathan Edwards' work "A Humble Attempt to Promote Explicit Agreement and Visible Union of God's People in Extraordinary Prayer for the Revival of Religion" (1747) explores the connection between united prayer and revival.

PRACTICAL APPLICATION: BECOMING DOERS OF THE WORD

JAMES 1:22-25 EXEGESIS

"Do not merely listen to the word, and so deceive yourselves. Do what it says. Anyone who listens to the word but does not do what it says is like someone who looks at his face in a mirror and, after looking at himself, goes away and immediately forgets what he looks like. But whoever looks intently into the perfect law that gives freedom, and continues in it—not forgetting what they have heard, but doing it—they will be blessed in what they do."

Key Greek Terms:

"Doers" (ποιηταὶ/poiētai) - performers, producers, those who put into practice
"Deceiving" (παραλογιζόμενοι/paralogizomenoi) - to reason falsely, to miscalculate, to delude
"Looks intently" (παρακύψας/parakupsas) - to stoop to look, to peer into with careful scrutiny

Theological Insight: James presents a stark contrast between passive hearing and active doing. The blessing comes not from knowledge alone but from applied knowledge.

APPLICATION EXERCISES

Unity Audit: As a group, evaluate your current unity level by discussing:
- Where do we experience the strongest sense of unity?
- What current issues or attitudes threaten our unity?
- How do we handle disagreements when they arise?
- What practical steps can we take to strengthen our unity?
Covenant Creation: Based on the sermon's closing corporate covenant, develop a specific unity covenant for your small group. Include commitments related to communication, conflict resolution, and mutual support.
Reconciliation Initiative: Is there someone you need to reconcile with? Make a specific plan to follow Matthew 18:15 this week. If appropriate, share your plan with the group for accountability.
Mission Discernment: If unity releases God's power for mission, what mission might God be calling your united group to pursue? Spend time in prayer discerning a specific outreach or service opportunity your group could engage in together.
Prayer Strategy: Develop a regular prayer practice focused on unity within your church. Consider praying through John 17 or using the "ACTS" model (Adoration, Confession, Thanksgiving, Supplication) with unity as a central theme.

DISCUSSION QUESTIONS

Personal Application: Which aspect of protecting unity is most challenging for you personally: refusing gossip, extending forgiveness, or focusing on essentials? What specific steps will you take to grow in this area?
Group Reflection: How might our small group become a model of unity for the larger church? What specific practices could we implement?
Church Application: What divisions or tensions do you observe in our church? Without gossiping, how might we constructively address these issues and contribute to greater unity?
Missional Impact: The sermon suggested that unity releases God's power for mission. What evidence of this have you seen in your own experience or in the history of our church?
Spiritual Formation: How might pursuing unity with other believers contribute to your personal spiritual growth? What character qualities need development?

CLOSING PRAYER AND COMMITMENT

Close your study time with prayer, specifically asking God to help your group apply what you've learned about unity.

Lord Jesus, you prayed that we would be one as You and the Father are one. We confess that we often fall short of this calling. Thank you for creating spiritual unity through your death and resurrection. Help us to live out that unity in practical ways. Make our group a testimony to your unifying power, and use our unity as a platform for your mission in our community. In your name we pray, Amen.
