13 And who is he who will harm you if you become followers of what is good? 14 But even if you should suffer for righteousness’ sake, you are blessed. “And do not be afraid of their threats, nor be troubled.” 15 But sanctify the Lord God in your hearts, and always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear; (1 Peter 3:13–15, NKJV)
Peter does not say Christians will be free from harm when we follow what is good. On the contrary, suffering for the sake of righteousness will happen. God blesses the Christian who endures such troubles and threats (cf. Matt. 5:10-12). Just as God assured Isaiah that He was his “sanctuary” (holy abode and sure protection) in the face of opposition, so the Lord is for us (v. 14; Isa. 8:12-14). As you “sanctify Christ as Lord in your heart” (NASB), you will be equipped with the necessary faith to be prepared to give an answer for your hope in Christ. So that, even when you suffer for what is good, you will not grow weary. If Christ is not Lord of your life, then you will not long endure suffering for the sake of what is right. Instead of faltering when defamed for being a Christian, let us say with Paul, “For this reason I also suffer these things; nevertheless I am not ashamed, for I know whom I have believed and am persuaded that He is able to keep what I have committed to Him until that Day” (2 Tim. 1:12).
