Many of God's jewels are crystallized tears.
(Isaiah 48:10 -- I have tested, refined, CHOSEN you in the furnace of affliction.)
It's a great comfort to remember in all our trials and difficulties that God has CHOSEN us. From our point of view our burdens sometimes seem as heavy as a tombstone to bury us. But God knows exactly the weight needed to keep the diver down so that he can search for pearls. When you feel "down," remember that God has CHOSEN you to gather pearls.
It has been said that many of God's jewels are crystallized tears.
(Isaiah 46:3-4) You are:
Chosen in Christ -- before the world
Called in Him -- out of the world
Justified in Him -- while in the world
To be glorified in Him -- beyond the world.
