Companion: Deep Study
A condensed companion to the full study. For each section of the expanded outline: key insights, applications, and the application questions for discussion.
Section 1 — Craving the Pure Milk of the Word (vv. 1–3)
Key Insights
- “Put away” the relational sins—malice, deceit, hypocrisy, envy, slander—that fracture fellowship.
- Crave the “pure spiritual milk” (the unadulterated Word) like a newborn craves milk, to “grow up into salvation.”
- Appetite follows experience: those who have “tasted that the Lord is good” (Ps. 34:8) hunger for more.
- The “Lord” of Psalm 34 is applied to Christ—an affirmation of His deity.
Applications
- Pair feeding on the Word with actively putting off sins of heart and tongue.
- Cultivate eager, regular intake of Scripture as genuine soul-nourishment.
- If appetite is weak, return to the goodness of Christ you first tasted.
Application Questions
- Do I crave God’s Word with the instinctive hunger of a newborn for milk, or has my appetite grown weak and occasional?
- Am I actively “putting away” malice, deceit, hypocrisy, envy, and slander, or do I tolerate these sins?
Section 2 — The Living Stone and Living Stones: A Spiritual House (vv. 4–8)
Key Insights
- Christ is the living Stone—”rejected by men but… chosen and precious” to God.
- Believers are living stones, built into a spiritual house and a holy priesthood offering spiritual sacrifices through Christ.
- Three stone-texts (Isa. 28:16; Ps. 118:22; Isa. 8:14) show Christ as cornerstone to believers and stumbling stone to the disobedient.
- Christ divides humanity; the disobedient stumble, “as they were destined to do”—divine sovereignty and human responsibility together.
Applications
- Build your entire life on Christ, not on foundations the world esteems.
- Live out your priestly calling—offer praise, service, and self to God through Christ.
- Recognize there is no neutrality toward Christ; respond in faith and warn others.
Application Questions
- Am I building my entire life on Christ the living Stone, or resting my security on foundations God has not appointed?
- Do I live as a member of God’s “holy priesthood,” or treat my faith as a private, passive possession?
Section 3 — A Chosen Race, a Royal Priesthood (vv. 9–10)
Key Insights
- Four titles (from Exod. 19:6; Isa. 43; Hosea) define the church: chosen race, royal priesthood, holy nation, God’s own possession.
- The purpose: to “proclaim the excellencies” of the God who called us from darkness to light.
- Conversion is being “called out of darkness into his marvelous light”—a sovereign, creative act.
- Once “not a people,” now “God’s people”; once without mercy, now recipients of mercy (Hosea fulfilled).
Applications
- Find your identity in God’s choosing love, not the world’s estimate.
- Fulfill your calling to proclaim God’s praises in worship and witness.
- Stay amazed at mercy—all you have rests on God’s undeserved compassion.
Application Questions
- Do I see myself as part of God’s chosen, royal, holy people, or do I let the world’s estimate define my identity?
- Am I fulfilling my calling to “proclaim the excellencies” of God, in worship and witness to those in darkness?
Section 4 — Sojourners with Honorable Conduct Among the Gentiles (vv. 11–12)
Key Insights
- As “sojourners and exiles,” abstain from “the passions of the flesh, which wage war against your soul”—the Christian life is inward warfare.
- Keep conduct honorable among outsiders, expecting slander.
- The answer to slander is a visibly good life that may lead accusers to “glorify God on the day of visitation.”
- Holiness and witness are joined: good deeds preach.
Applications
- Wage deliberate, Spirit-empowered war against besetting sins.
- Respond to slander not with retaliation but with persistent good conduct.
- Remember your good works are a public witness that can lead others to glorify God.
Application Questions
- Am I actively waging war against the “passions of the flesh,” or have I made peace with sins seeking to destroy my soul?
- When misunderstood or slandered for my faith, do I retaliate, or respond with conduct that glorifies God?
Section 5 — Submission for the Lord’s Sake to Human Institutions (vv. 13–17)
Key Insights
- Submit to governing authorities “for the Lord’s sake”—even under Nero; government is God-ordained to punish evil and praise good.
- Christian freedom is never “a cover-up for evil”; the free are “servants of God.”
- Four duties: honor everyone, love the brotherhood, fear God, honor the emperor.
- Only God receives fear (worship); the ruler receives honor—marking the limits of human authority.
Applications
- Be a model citizen—obeying laws, honoring officials—within the bounds of obedience to God.
- Use liberty to serve God, not to indulge sin or despise authority.
- When the state demands worship or commands sin, “obey God rather than men.”
Application Questions
- Am I known as one who submits to and honors legitimate authority “for the Lord’s sake,” or do I have a grumbling, rebellious spirit?
- Do I use my Christian freedom as a cover for self-indulgence, or live as a “servant of God,” free yet glad to submit?
Section 6 — Servants and Unjust Suffering: Following Christ’s Steps (vv. 18–21)
Key Insights
- Servants are to submit even to unjust masters, bearing wrong “mindful of God.”
- Patient endurance of undeserved suffering is “a gracious thing” in God’s sight; deserved punishment earns no credit.
- We are “called” to this, for “Christ also suffered for you, leaving you an example.”
- Christ is both pattern (example to trace) and substitute (“suffered for you”).
Applications
- When wronged, endure “mindful of God,” offering it to Him as worship.
- Distinguish suffering for doing good from the just consequences of your own sin.
- Follow Christ’s steps, resting on the atonement that empowers the imitation.
Application Questions
- When I suffer unjustly, do I endure it “mindful of God,” or respond with resentment, retaliation, or self-pity?
- Am I careful to distinguish suffering for doing good from suffering that is the just consequence of my own sin?
Section 7 — Christ Our Substitute and Shepherd (vv. 22–25)
Key Insights
- Drawing on Isaiah 53: Christ was sinless (“committed no sin”), non-retaliating (“did not revile in return”), entrusting Himself to him who judges justly.
- “He himself bore our sins in his body on the tree”—penal, substitutionary atonement.
- The atonement aims at transformation: “that we might die to sin and live to righteousness.”
- Straying sheep have “returned to the Shepherd and Overseer of your souls.”
Applications
- When wronged, entrust yourself and your cause to God the righteous Judge.
- Let the cross shape your battle against sin—Christ bore it to free you from it.
- Rest in Christ the Shepherd who sought you, healed you, and guards your soul.
Application Questions
- When I am wronged, do I follow Christ in “entrusting myself to him who judges justly,” or take vindication into my own hands?
- Does the truth that Christ “bore our sins… that we might die to sin and live to righteousness” actually shape my battle against sin?
Christ-centered takeaway: Built on Christ the rejected-yet-chosen Cornerstone, believers are God’s chosen race and royal priesthood, called from darkness to declare His praise; as sojourners they live honorably, submit for the Lord’s sake, and follow the steps of the Suffering Servant who bore their sins and shepherds their souls.
