When God takes away something precious from us, it's for a reason. Usually it's because we need to be disciplined, or taught the value of something we were taking for granted, or steered out of trouble into a safer direction.

The Jews have never satisfactorily explained why they lost everything 2000 years ago. Their standard answer has been that they were victims of their enemies - that their entire history has been plagued by enemies who are out to destroy them. They long for the day when God will vindicate them and return them to their home and Biblical roots. We don't need the physical anymore. It has served its purpose; the lessons are now recorded in the Old Testament for all to learn. Those lessons are stepping stones, a primer to something better. Why long for the shadow when you can have the real thing? And he carried me away in the Spirit to a mountain great and high, and showed me the Holy City, Jerusalem, coming down out of Heaven from God. But you have come to Mount Zion, to the Heavenly Jerusalem, the city of the living God.
