The expectation is that by engaging God's word (1 Peter 2:2) we will grow in salvation and growing we will be continually formed into the unique people of God. Being the people of God affects our relationship to this world. We are now aliens and strangers, and we make deliberate choices to keep the identity of our true homeland.
The middle of the chapter speeds up with staccato instruction. . . "love the brotherhood, fear God, honor the king." These things describe what doing good means (1 Peter 2:15).
The other stunning thing is that we can expect to suffer. Jesus left us a patter so that we can walk in his footsteps.
