Our past mistakes and sins have a reason::

I often find myself wondering in frustration how the Lord will be using my struggles in my past mistakes  to glorify him in the future

The damage is done I know I still have the scars in my hunting memory.

And I don't understand fully how the Lord will use that in my life to bring others closer to him.

We may never know how The Lord will use the good and the bad in our lives for his greater glory.
