"Therefore, this is what the Lord 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."

In this life we will face many great sorrows, some caused by others, and some we cause ourselves. There is no way to avoid all failings and sorrows. And each of us will do things that are "worthless" or have things happen to us. But the promise gives us our answer, "return to Him, and restoration will come", we are to extract the precious from the worthless and make the best use of what remains."
