Peter is writing to Hebrew exiles north of Israel in the Black Sea region. He assures them that they have an inheritance that for now is in Heaven but will be possessed at the coming of Christ. He also says that the trials that they are currently experiencing are to prove their faith.
Peter assures his readers that they have not been cast off by Christ and that they will be living stones in the edifice of which Christ is the cornerstone. In this he urges them to be good citizens of the places where they are exiles; both for their own good and as a witness for the Gospel.
Peter exhorts his readers to good conduct, first in the family, then in the exile community and finally in society at large. This is to serve several purposes. First, because it is pleasing to God. Then that it will strengthen the family and the exiles. A bad example will also hinder the spread of the Gospel. Finally, it is the best defense against persecution. Although persecution may come, it is best not to deserve it.

! Peter closes with an exhortation to good behavior especially in the face of worldly persecution. 2 Peter opens with the description of a process or algorithm for increasing ones fruitfulness in the Kingdom of God.
After having instructed his readers on the way to godliness, Peter switches to warning them about false prophets and teachers. These, he says, will preach sensuality which will be attractive to those who are unaware or are so inclined. Those who follow such teachers will wind up worse off than if they had never know Christ.
Peter closes out his letter with an exhortation not to be led astray by scoffers who mock the belief that Christ will return and establish His reign of righteousness. He assures his readers that, just as God destroyed the previous creation with a flood, He will destroy the present one by fire and create a new heaven and earth.
