Real Christmas Joy
By Mrs Mary Rollins Britton
You must get well, my darling girl,
For Christmas is on the way.
Santa must find you big and strong,
You are eight years old today.
Think what Santa will bring you,
Think how we all love you too.
And try hard to get well, dear,
You will, little girl, won't you?
"Yes, Mumie, but I'm so sleepy,
So tired,” she said with a sigh,
"But I'll be better tomorrow,
Be better in morning, bye".
In her dreams she played with angels,
In Heaven she heard them sing.
But way off mother was calling,
And the vesper bells did ring.
And the music of their message,
Came over so bright and clear.
She was still on earth with mother,
And Christmas was very near.
“I'll be right back in a minute’’,
Ann murmured so soft and low,
But mother heard and held her tight,
She could never let her go.
And when the dream was over,
New life seemed to surge and play.
She would be well and strong again,
On the coming Christmas Day.
But that glimpse she had of Heaven,
Will linger sweet through each day.
And make her pathway bright and clear,
Someday, she’ll go back to stay.
