Footsteps in the Sand is a very well known poem. It describes a man's experience of walking along the beach with God and as they go, they leave footprints behind them.
The footprints represent all that the man has experienced in his past but during the times he needed God the most, there were only one set of prints which led him to ask why he was abandoned during those times.
God answers his question at the end of the poem.
Footsteps in the Sand
One night I dreamed a dream.
As I was walking along the beach with my Lord.
Across the dark sky flashed scenes from my life.
For each scene, I noticed two sets of footprints in the sand,
One belonging to me and one to my Lord.
After the last scene of my life flashed before me,
I looked back at the footprints in the sand.
I noticed that at many times along the path of my life,
especially at the very lowest and saddest times,
there was only one set of footprints.
This really troubled me, so I asked the Lord about it.
"Lord, you said once I decided to follow you,
You'd walk with me all the way.
But I noticed that during the saddest and most troublesome times of my life, there was only one set of footprints.
I don't understand why, when I needed You the most, You would leave me."
He whispered, "My precious child, I love you and will never leave you
Never, ever, during your trials and testings.
When you saw only one set of footprints,
It was then that I carried you."
