Foot Prints

One night I had a dream. I dreamed I was walking along the beach with God and across the sky flashed scenes from my life. For each scene I noticed two sets of footprints in the sand, one belonged to me, the other to God. When the last scene of my life flashed before me, I looked back at the footprints in the sand. I noticed that many times along the path of life, there was only one set of footprints.
I also noticed that it happened at the very lowest and saddest times in my life. This really bothered me and I questioned God about it. "God, you said that once I decided to follow you, you would walk with me all the way, but I noticed that during the most troublesome times in my life there is only one set of footprints.
I don't understand why in the times when I needed you most, you would leave me?" God replied, "My precious precious child, I love you and I would never never leave you during your times of trials and suffering. When you see only one set of footprints it was then that I carried you."
