“But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:” (1 Peter 3:15, KJV).

In its setting, Peter is speaking to believers who are living as strangers and pilgrims in a world that may misunderstand them, oppose them, or even punish them for doing well. The verses around it speak of suffering “for righteousness’ sake,” of being “not afraid of their terror, neither be troubled,” and of maintaining a good conscience so that accusations against the Christian life are put to shame by the believer’s consistent conduct. 1 Peter 3:15 sits like a hinge in that flow: it shows what is to be happening inside the heart when pressure comes from the outside, and what must then be expressed from the mouth and life when questions arise.

The command, “sanctify the Lord God in your hearts,” does not mean making God holier than He is, but setting Him apart within the inner man as the supreme reality and rightful ruler. To sanctify Him in the heart is to enthrone Him there, to treat His will as weightier than fear, His word as steadier than rumor, and His approval as more decisive than the verdicts of men. In the KJV phrasing, the heart is the center of thought, desire, and resolve; Peter is insisting that faithful witness begins not with argument but with worship. The believer’s first act under threat is inward consecration: to regard “the Lord God” as Lord indeed. This is also a quiet reversal of the surrounding anxiety of the passage. Instead of letting adversaries set the agenda by terror, the Christian lets God set the agenda by reverence. Fear is not absent from the verse, but it is redirected: the heart that sanctifies the Lord learns whom to fear, and therefore whom not to fear.

From that inward sanctification flows the outward readiness: “be ready always to give an answer.” The “answer” here is the believer’s reply when asked why he lives as he does, hopes as he does, endures as he does. In context, Christians are not portrayed as combative people looking for quarrels, but as people whose life, patience, and purity become so conspicuous under trial that others “ask” about it. That asking can be honest curiosity, puzzled observation, or hostile interrogation; Peter’s wording allows for all. Yet the Christian is to be “ready always,” not improvising faith only when cornered, but living with a settled grasp of the gospel such that speech can rise naturally when called for. Readiness implies thoughtfulness, memory of God’s promises, and a practiced ability to speak plainly without betraying either truth or charity.

The content of this answer is “a reason of the hope that is in you.” Hope, in Peter, is not optimism, but expectation grounded in what God has done and will do: the believer’s living hope through the resurrection, the inheritance reserved in heaven, the final salvation ready to be revealed. This hope is “in you,” not as a private mood but as an implanted confidence that shapes behavior. The world can often tolerate private beliefs that have no visible effect; Peter assumes Christian hope will show itself so unmistakably that it provokes questions. Hope becomes, in a sense, symbolic: it is the inward lamp that keeps burning when circumstances argue for despair. In suffering, hope is the believer’s contradiction of appearances, a testimony that present affliction is not the final word. The “reason” for that hope is therefore not merely a set of philosophical proofs; it is the gospel rationale: God’s promise, Christ’s work, and the believer’s union with Him. The verse presumes that hope has intelligible content that can be spoken, not merely felt.

Peter then governs the manner of the answer: “with meekness and fear.” Meekness is strength under restraint, a refusal to answer pride with pride, accusation with scorn, or mockery with contempt. It is the temper of Christlike gentleness, not the weakness of silence when truth is needed, but the discipline of speaking truth without the heat of self-importance. The “fear” here stands in harmony with the first clause. It is not fear of man that paralyzes, but reverent fear—an awareness that one speaks in the presence of God, that one’s words represent Him, and that careless speech can dishonor the Lord who has been sanctified in the heart. This fear also guards against turning defense into display. The Christian is not called to win admiration, but to be faithful; not to crush an opponent, but to point to the Lord with a clean conscience. In the wider context, this reverence includes moral seriousness: a life consistent with the confession, so that the “answer” is not contradicted by the witness of conduct.

Taken together, the verse describes a movement from inward worship to outward witness. The heart becomes a sanctuary where “the Lord God” is set apart; the mind becomes prepared to speak; the life becomes a visible carrier of hope; the mouth becomes an instrument of gentle truth; and the whole person becomes governed by reverence rather than intimidation. The significance of 1 Peter 3:15 is that it joins doctrine, devotion, and demeanor. It refuses the separation of faith from speech, or speech from character, or character from worship. In a hostile or questioning world, it teaches that the most persuasive “answer” is not merely a clever response, but the steady, sanctified heart that fears God, hopes in Him, and therefore can speak with meekness when asked why.
