But even if you should suffer for righteousness' sake, you are blessed. "Don't fear what they fear, neither be troubled."
and be not afraid of their terror: Literally, Christians are not to fear the fear or threats that enemies of Christ attempt to throw out (Isaiah 8:12-13). (Compare 3:6.) Rather, Peter says they should be calm, be composed even in the face of fiery trials; God is for those who belong to Him.
