Isaiah 48:10

By allowing the Babylonian exile, God was not casting off His people, but disciplining them so they would come to their senses, and follow Him more faithfully thereafter. The difficult times Israel had been through were fires of refining, not fires of destruction. Fire was one of Isaiah’s favorite figures for judgment, and often it was God’s people whom he described as in the fire. Unfortunately many readers think only of hell when they read of judgment fire in Scripture. In refining silver, the craftsman burns away all the dross. If God had refined Israel that way, there would have been nothing left of the nation. Affliction is a sign that God has chosen and loves His people; it is not a sign that He has not chosen and does not love them (cf. Hebrews 12:3-13).
