Dr. John MacArthur writes - William Barclay noted that George Reindrop in his book No Common Task tells how a nurse taught one man to pray and in doing so changed his whole life. A dull, disgruntled, and dispirited man became a man of joy. Much of the nurse's work was done with her hands, and she used her hand as a scheme of prayer.Each finger stood for someone.
Her thumb was nearest to her, and it reminded her to pray for those who were closest and dearest to her.
The second finger was used for pointing and stood for all her teachers in school and the hospital.
The third finger was the tallest and it stood for the V. I. P. s, the leaders in every sphere of life.
The fourth finger was the weakest, as every pianist knows, and it stood for those who were in trouble and in pain.
The little finger was the smallest and the least important and to the nurse it stood for herself"
