Then I will restore (make-up) to you the years that the locusts have eaten (Joel 2:25).
I love interpreting this verse metaphorically in order to apply it to my own life.
We have all had periods in our lives where we have wasted days, even years on being angry, or timid, or sulky, or fearful, or whiney, or even mentally checking-out. Later we regret those times especially if there is a person involved who is no longer with us.
In many instances a do-over is not possible, but God is able and can somehow compensate. He is so gracious to those who put their faith in Him, and with Him nothing is impossible. After all, it is not God that invades our peace, but it is Him who can lead us to still waters and can more than satisfy the ache in our soul.
