Peter's second letter refers appreciatively to Paul's letters in 3:15-16, but bears no hint that Paul is dead. On the other hand, Peter seems to anticipate his own death. Soon (see 1:13-14). Scholars therefore date this letter in the same decade of the sixties—but closer to the end.
This letter does not tell us how to escape suffering, but instead to expect it. It shows us that throughout suffering we can enjoy our fellowship with other believers and look forward to a new heaven and a new earth, a "home of righteousness," with an end to pain.
