The fiery trials have many purposes. They will reveal to you the thorns and splinters of darkness that remain within you. Then you will know to repent and allow the splinters to be burned as you become a living sacrifice for those who are around you, and for those who are being used by the enemy to cause the fire.
1 Peter 4:12-13 Beloved, do not think it strange concerning the fiery trial which is to try you, as though some strange thing happened to you; but rejoice to the extent that you partake of Christ’s sufferings, that when His glory is revealed, you may also be glad with exceeding joy.
