Teaching Outline: 1 Peter 1:15–16 (LSB)

“But like the Holy One who called you, be holy yourselves also in all your conduct; because it is written, ‘YOU SHALL BE HOLY, FOR I AM HOLY.’”

**I. The Contrast: “But…” (v. 15a)

Observations                                                                                                                

• “But” contrasts the former life of ignorance (v. 14) with the new life of holiness.
• Peter shifts from what believers must not be (conformed to old desires) to what they must be (holy).

Interpretation

• Christian holiness is not merely avoidance of sin but active conformity to God’s character.
• The gospel creates a decisive break with the past.

Cross References

• Romans 6:4 — walk in newness of life.
• Ephesians 4:22–24 — put off the old self, put on the new.

Application

• Don’t settle for “not sinning”; pursue the positive beauty of holiness.

**II. The Standard of Holiness: “Like the Holy One who called you” (v. 15b)

Observations

• God Himself is the model and measure of holiness.
• Holiness is rooted in God’s nature, not cultural norms or personal preference.
• The call to holiness flows from God’s prior call to salvation.

Interpretation

• Holiness is relational—children resemble their Father (v. 14).
• God’s call creates both the identity and the obligation of holiness.

**III. The Scope of Holiness: “Be holy… in all your conduct” (v. 15c)

Observations

• Holiness is comprehensive—“all your conduct,” not selective or compartmentalized.
• Peter emphasizes lifestyle, not isolated religious acts.

Interpretation

• Holiness touches every sphere: speech, relationships, work, desires, habits, private life.

**IV. The Scriptural Foundation: “Because it is written…” (v. 16a)

Observations

• Peter grounds his command in Scripture, quoting Leviticus.
• Holiness is not a new idea; it is the consistent demand of God’s covenant.

Observations

• God’s holiness is the reason believers must be holy.
• Holiness is imitation of God’s character.

Interpretation

• Holiness is not legalism—it is God‑likeness.
• God’s nature shapes the believer’s nature; His character becomes the believer’s calling.

One‑Sentence Summary

Peter commands believers to reflect God’s own holiness in every part of life because the God who called them is holy and has always required His people to be holy.

100‑Word Video Script (1 Peter 1:13–25 Context)

Peter calls believers to a radically different way of life. In 1:15–16, he says holiness isn’t optional—it’s the lifestyle that reflects the God who saved us. We’re not shaped by old desires anymore; we’re shaped by the Holy One who called us. Holiness touches every part of life because God’s character defines our conduct. Peter anchors this command in Scripture: “Be holy, for I am holy.” In the flow of 1:13–25, holiness grows from hope, redemption, and the new birth. Because Christ redeemed us with His precious blood, we live as people who display God’s purity in a dark world.
