Unless ye become as little children ye cannot enter the kingdom of Heaven. To become pure as a child is the command. Not only pure from sin, but purified from doubt; the doubt of God's omnipotent care. Little children do not doubt the truth as set forth in Christian Science, but go right to work to prove it.
My little boy, eight years old, was out walking with his Grandpa, little brother and sister. While passing a neighbor's house, Grandpa was called in to a man who was dangerously ill from cramps and violent retchings, in which condition he had been for some hours. He required immediate relief, and Grandpa said, he would not have given two cents for his chances of recovery. Home remedies and applications had been tried without success, and the only thing left to do (seemingly) was to call a doctor, with all possible speed, which Grandpa proceeded to do. But one remedy had been overlooked! Little Albert goes to a Christian Science Sunday School where he learns that "God is All-power," and "an ever-present help in time of trouble." He was standing in the room, unobserved, waiting for Grandpa's return. Knowing the "Scientific Statement of Being," he repeated it silently, and had hardly finished when the sick man was relieved, and sat up and vomited, and said, I am all right." When the doctor came, the man said, "I don't want any medicine, I am all right."
Albert came home and told his mamma and papa (both of whom have been healed in Christian Science, and think the world of it) about his demonstration, never doubting for a moment that the cure was the result of the little Light which he reflected. Thus little children are become our leaders; without a fear, without a doubt they take the word of God and demonstrate it.
