I remember one night when I was taking care of a couple of our grandchildren. It was late in the evening, but since grandfathers usually let their grandchildren stay up longer than they should, they were still awake.
We were laughing, messing around, and having a great time together when we suddenly heard a knock on the door. Not the doorbell, but a mysterious knocking. Immediately one of my grandsons grabbed hold of my arm.
"It's OK," I said. The knock came again, and I started to the door. My grandson followed me, but he hung on to my left leg and hid behind me as I opened the door.
It was one of my son's friends who had dropped by unexpectedly. After the person had left and I'd closed the door, my grandson, still holding on to my leg, said in a strong voice, "Bubba, we don't have anything to worry about, do we?"
And I said, "No, we don't have anything to worry about. Everything's fine."
You know why he was strong? Because he was hanging on to protection. As long as he was clinging to grandfather's leg, he didn't have to worry about a thing.
