We were never promised a good and easy life, and if we know that it should reframe the way we live our lives when hard times come.  Peter is helping us to rethink all the pain that we will endure in this life.

1 Peter 4:12-13 "Beloved, do not be surprised at the fiery trial when it comes upon you to test you, as though something strange were happening to you.  But rejoice insofar as you share Christ's sufferings, that you may also rejoice and be glad when his glory is revealed."
