The whole point Peter is making is to be Christ like, no matter the fairness of the attitudes or actions against us by whomever in our lives, be it government, workplace people, friends, or even family. Isaiah in this passage shows Christ suffering and remaining silent. Silence was His testimony to the unbelievers, the way of His Father. The passage shows that Christ knew that he was to suffer and die before he even put aside His glory and came to earth as man. It was an absolute decision making process, that we see followed through by our Saviour for us, even, or especially with His foreknowledge of events to come. We have no idea about what may befall us, and in fact, our lives may be quite easy compared to many others in the world, so even if we make a decision to live 1 Peter 2:13-25, we are not even coming close to the decision that Christ made. After all, our suffering is only our own and a few around us, His suffering was for the whole world, and every sin that was, that had been and is to come. There are powerful human examples, such as the story of 'The Heavenly Man' Liu Zhenying, known as Brother Yun. We may think of Brother Andrew in Russia, though his story is more about doing something against a government and suffering for his faith. I am not sure if any of you have read or know of the massacre of five Amish school girls in the Nickel Mines school (2 October 2006). The community's Christlike attitude in forgiveness and support to those that harmed them was phenomenal. It is a story that makes one weep as one sees a group who can submit and forgive despite the worst of circumstances, setting aside the Amish context, focusing on the Christlike response.
