"but in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect."
1 Peter 3:13-14 is an allusion to Isaiah 8. A connection is made with Isaiah 8:13:
“But the Lord of hosts, him you shall honor as holy. Let him be your fear, and let him be your dread."
Peter substitutes the Old Testament phrase "the Lord of hosts" with "Christ the Lord," thereby proving that he believed Jesus Christ to be God in the flesh. We are to honor Him as the Holy One.
