1Pe 4:12-14
"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."
Suffering is not an exception — it is the norm of Christian life in this age. 'Do not be surprised' (me xenizesthe) — do not be strangers to suffering. Sharing in Christ’s sufferings is sharing in His future glory. The parousia will transform present suffering into eternal joy.
