2025-09-21 Life Group Leader’s Guide
Getting to Know You
Question 1: How is it that a young believer and a mature believer can both be fed by the same Scripture? How has your understanding of God’s word grown? (cf. Heb 5:12–14; 1 Cor 3:1–2)
Commentary Insights
Leader tip: Invite a newer and a seasoned believer to share how the same verse has met them differently this year.
Digging Deeper
Question: Read Isa 40:8; Isa 55:11; Matt 5:17–18; Matt 24:35; John 14:26. What does the Bible claim about itself? How can the miraculous preservation of the Scriptures be used as an apologetic when witnessing to the lost?
Commentary Insights
Apologetics Angle
Question: Read Ps 18:30; Ps 119:9; 119:105–107; Prov 30:5; John 8:31–32; 2 Tim 3:16–17. Why did the Scriptures need to be accurately preserved? What would be the result if they weren’t?
Commentary Insights
If not preserved: doctrine drifts, counsel becomes opinion, and confidence in God’s promises erodes. (NIV Application Commentary)
Question: Read Josh 4:4–7; Ezek 36:22–24; John 13:35; John 17:23. Consider evidences for Christianity (science, archaeology, the Bible’s composition/preservation, fulfilled prophecy, Israel’s rebirth, regeneration). How does this wide array of evidence strengthen the case for Christianity? Why do we need reminders like Joshua’s stones?
Commentary Insights
Why reminders? We are forgetful; memorials rehearse God’s acts, shape identity, and catalyze conversations with the next generation. (Wiersbe, Be Series; Life Application Bible Commentary)

Question 1: How is it that a young believer and a mature believer can both be fed by the same Scripture? How has your understanding of God’s word grown? (cf. Heb 5:12–14; 1 Cor 3:1–2)
Commentary Insights
- Matthew Henry: God’s Word is “an inexhaustible store”—the same passage offers “milk” to the young and “strong meat” to the mature because the Spirit applies it according to each person’s condition. (Matthew Henry)
- Wiersbe, “Be” Series: Scripture is living food; as we obey the light we have, God gives more light. Growth turns familiar verses into deeper pathways of trust and obedience. (Warren Wiersbe, Be Series)
- NIV Application Commentary: Meaning is stable, but significance grows with life stage; the Spirit brings new implications from the same unchanging text as contexts change. (NIV Application Commentary)
- Life Application Bible Commentary: Application scales—beginners find clear next steps; seasoned believers are challenged in motives, priorities, and leadership. (Life Application Bible Commentary)
Leader tip: Invite a newer and a seasoned believer to share how the same verse has met them differently this year.
Digging Deeper
Question: Read Isa 40:8; Isa 55:11; Matt 5:17–18; Matt 24:35; John 14:26. What does the Bible claim about itself? How can the miraculous preservation of the Scriptures be used as an apologetic when witnessing to the lost?
Commentary Insights
- Bible Knowledge Commentary (Isa 40:8; Matt 24:35): Scripture insists on its permanence—God’s Word “stands forever” and outlasts creation; Jesus places His words on that same enduring level. (Bible Knowledge Commentary)
- The Expositor’s Bible Commentary (Isa 55:11): God’s Word is effective—it accomplishes the divine purpose; its power is not in human eloquence but in God who sends it. (Expositor’s Bible Commentary)
- Holman OT/NT Commentary (Matt 5:17–18): Jesus affirmed the authority and reliability of the OT down to the smallest letter; He fulfills rather than abolishes it, anchoring Christian confidence in verbal reliability. (Holman Commentary)
- NIV Application Commentary (John 14:26): The Spirit’s ministry to the apostles ensured accurate recall and teaching, undergirding the trustworthy foundation of the NT witness. (NIV Application Commentary)
Apologetics Angle
- Expositor’s Bible Commentary: The Bible’s textual preservation (abundance and early dating of manuscripts; stability across copies) makes it uniquely verifiable among ancient texts—supporting its self-claims when sharing with skeptics. (Expositor’s Bible Commentary)
- Bible Knowledge Commentary: Combine preservation with fulfilled prophecy and Christ’s view of Scripture for a cumulative case: if Jesus rose and treated Scripture as God’s Word, His authority validates the Bible’s authority. (Bible Knowledge Commentary)
Question: Read Ps 18:30; Ps 119:9; 119:105–107; Prov 30:5; John 8:31–32; 2 Tim 3:16–17. Why did the Scriptures need to be accurately preserved? What would be the result if they weren’t?
Commentary Insights
- Tyndale OT/NT Commentaries (Ps 18:30; Prov 30:5): God’s way is perfect and His word is tested/pure; a pure God cannot guide with a corrupted word—preservation guards His character’s reputation. (Tyndale Commentaries)
- Life Application Bible Commentary (Ps 119; John 8:31–32): Scripture directs daily steps and forms disciples who abide in Christ; distortion would mislead decisions and stunt spiritual freedom. (Life Application Bible Commentary)
- Wiersbe, “Be” Series (2 Tim 3:16–17): Because Scripture is God-breathed and equips every believer for every good work, accuracy is essential; corruption would undercut doctrine, reproof, correction, and training. (Warren Wiersbe, Be Series)
- Holman Commentary: If the text were unreliable, assurance of salvation, moral guidance, and church unity would fracture; preservation sustains teaching and mission. (Holman Commentary)
If not preserved: doctrine drifts, counsel becomes opinion, and confidence in God’s promises erodes. (NIV Application Commentary)
Question: Read Josh 4:4–7; Ezek 36:22–24; John 13:35; John 17:23. Consider evidences for Christianity (science, archaeology, the Bible’s composition/preservation, fulfilled prophecy, Israel’s rebirth, regeneration). How does this wide array of evidence strengthen the case for Christianity? Why do we need reminders like Joshua’s stones?
Commentary Insights
- Bible Knowledge Commentary (Josh 4): The memorial stones functioned as public, intergenerational reminders so future questions would prompt testimony—memory devices strengthen faith and witness. (Bible Knowledge Commentary)
- NIV Application Commentary (John 13:35; 17:23): Love and visible unity among believers serve as living apologetics—tangible evidence that the Father sent the Son. (NIV Application Commentary)
- Expositor’s Bible Commentary (Ezek 36): God’s restoration promises display His holiness among the nations; historical movements of Israel and ongoing work among His people point beyond human explanation to divine fidelity. (Expositor’s Bible Commentary)
- Holman Commentary: Christianity invites a cumulative case: converging lines from creation’s order, archaeological corroborations, textual preservation, prophecy, and transformed lives together form a robust, courtroom-style argument. (Holman Commentary)
Why reminders? We are forgetful; memorials rehearse God’s acts, shape identity, and catalyze conversations with the next generation. (Wiersbe, Be Series; Life Application Bible Commentary)
Taking It Home
Question: How has this study personally impacted your faith? Who can you share this with this week?
Reflection & Application
- Matthew Henry: Turn truth into praise—thank God for a Word that stands when everything else shifts. (Matthew Henry)
- Life Application Bible Commentary: Choose one “memorial” practice this week (journal entry, shared testimony, or Scripture card) and one person to share it with. (Life Application Bible Commentary)
Leader’s Prompt Ideas
- Have the group pick one verse from the set and name a “milk” application for a new believer and a “meat” challenge for a mature believer.
- Close by praying 2 Tim 3:16–17 over the group’s week.
