Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you:
Strange - they might think it strange that God should allow His chosen children to be sore tried.
Fiery trial - like the fire by which metals are tested and their dross removed. The Greek adds 'in the case.'
Which is to try you - Greek, 'which is taking place for a trial to you.' Instead of its 'happening to you' as some strange chance, it 'is taking place' with tile gracious design of trying you: a consolatory reflection.
