We may suffer for many reasons. Some suffering is the direct result of our own sin, some happens because of our foolishness, and some is the result of living in a fallen world.
Peter is writing about suffering that comes as a result of doing good. Christ never sinned, and yet he suffered so that we could be set free. When we follow Christ’s example and live for others, we too may suffer.
Our goal should be to face suffering as he did-with patience, calmness, and confidence that God is in control of the future.
1 Peter 2:21-22 For God called you to do good, even if it means suffering, just as Christ suffered for you. He is your example, and you must follow in his steps.22He never sinned,nor ever deceived anyone.
