"If you extract the precious from the worthless, 

you will become my spokesman." Jer. 15:19 

That verse struck me, it reminds me of Romans 8:28

The verse in its entirety says - 

"If you return, then I will restore you --

You will stand before me; 

and if you extract the precious from the worthless,

you will become my spokesman." 

 "We all stumble in many ways", and life can be so harsh for some, words fail to describe; but if we return to the Lord He will reveal the precious soul shaping lessons in even the most tragic circumstances, and those precious things will tune your heart to the needs of others and you will have a message to speak.
