It is a serious tender mercy to me when I step on the scale in the morning after eating a brownie and icecream the night before and being down a pound. Seriously.
Even though the physics of it might not make sense, I feel like the Lord knew I needed that brownie. He also knew I could not emotionally handle my pants being one bit tighter. And that is a tender mercy to me.
