when He chooses grace

Yesterday as I was walking in the house, I noticed one of the kiddos had left some of their trading cards on the bumper of my car. I had a choice at that point to move them, or to let the child suffer the consequences of their neglect when the cards were damaged in the road or in the rain.
I don't always, but this time, I chose grace. I didn't put the cards away, I just moved them somewhere safer. and my child won't even notice, nor will I ask them to.
It made me wonder how many times my Heavenly Father does the same for me. How many acts of his kindness go unnoticed? How many times does he move things around in my life to keep me safe, or to protect my heart when I don't even know He's moving? How many times does he display kindness without expecting thankfulness in return, just because He is good?
