This is a key passage instructing Christians to be prepared to defend their faith. Peter begins by exhorting us: “in your hearts set apart Christ as Lord.” Apologetics must flow from a relationship with Christ as Lord. Peter assumes that Christians will have enough contact with unbelievers that they will be asked to give the reason for the hope that they have and he urges us to be prepared to do so.
