📖 Verse-by-Verse Commentary
1 Peter 1:13 — Gird Up Your Minds
“Therefore gird up the loins of your mind, be sober, and rest your hope fully upon the grace that is to be brought to you…”
Peter calls for mental readiness and disciplined focus. Believers must set their hope firmly on future grace, not present ease.
1 Peter 1:14–16 — Called to Holiness
“As obedient children, not conforming yourselves to the former lusts… but as He who called you is holy, you also be holy in all your conduct…”
The Christian’s identity as God’s children demands likeness to the Father. Holiness is not optional; it flows from belonging to a holy God. Peter cites Leviticus: “Be holy, for I am holy.”
1 Peter 1:17 — Conduct in Reverence
“And if you call on the Father… conduct yourselves throughout the time of your stay here in fear…”
God’s role as impartial judge calls believers to live with reverent awe. This fear is not terror but deep respect, recognizing accountability to the Father.
1 Peter 1:18–19 — Redeemed by Christ’s Blood
“…knowing that you were not redeemed with corruptible things, like silver or gold… but with the precious blood of Christ, as of a lamb without blemish and without spot.”
Redemption is costly. The blood of Christ surpasses any earthly payment, fulfilling Old Testament imagery of the spotless sacrificial lamb.
1 Peter 1:20–21 — Christ Foreknown and Revealed
“He indeed was foreordained before the foundation of the world, but was manifest in these last times for you…”
Christ’s sacrifice was not an afterthought. God’s eternal plan included His Son, revealed now for believers who through Him trust in God, who raised Him from the dead.
