One of Jason's favorite books was about a little steam locomotive named Tootle. ^{Gertrude Crampton, Tootle, collected in A Treasury of Little Golden Books (New York: Golden Press, 1960), pp. 16–19 .}

Tootle wanted to grow up to be a good steam train that people could depend on to be safe and reliable for trips between two big cities. He had to go to school and take courses in train subjects, like "Pulling the Diner Without Spilling the Soup," "Puffing Loudly When Starting," and "Stopping for a Red Flag Waving." Tootle had to do well in all subjects, but there was one subject he had to do perfectly.

It was "Staying on the Rails No Matter What." The book tells how Tootle learned this subject the hard way.

Sometimes Jason and his mom talked about "Staying on the Rails No Matter What." They decided that praying and trusting God were the very best way for them to stay "on the rails"—on the track. They talked about staying on the track, because Jason had a train set and liked to put the pieces of track together. They said when you stay on the track you are staying with God. When you pray you listen to God and try to see only good, the way God sees only good.

One time when Jason was on vacation with his mom, dad, grand mother, grandfather, and other relatives, he began to have itches on different parts of his body. Jason and his parents prayed. They wanted to stay very sure that Jason really was God's child, pure and good in every way. They knew that praying would keep them on the track, where they wanted to be. Jason didn't believe that itches could really be any part of God's child. He was happy to remember that he was God's child and to love being perfect!

Then the itches disappeared everywhere except on his face, where they seemed to get worse. One day even his eyes were itchy and puffy.

Jason was tempted to be discouraged then—to get off the track—to be afraid and to believe the picture of itches he saw in a mirror. But Jason and his mom and dad knew that they couldn't be tricked. So together they prayed more, and they kept on trusting God.

They thought about Christ Jesus and how he had stayed on the track—trusting God—no matter what picture he saw. And this resulted in Jesus' healing—of a blind man, ^{See John 9:1–7 .} a sick little girl, ^{See Luke 8:41, 42, 49-56 .} and a man who could not speak. ^{See Matt. 9:32, 33 .} Mrs. Eddy says in Science and Health: "Jesus beheld in Science the perfect man, who appeared to him where sinning mortal man appears to mortals. In this perfect man the Saviour saw God's own likeness, and this correct view of man healed the sick." ^{Science and Health, pp. 476-477.}

Jason felt happy again. He prayed to see what God (not the mirror) was telling him—that he was spiritual and whole and pure. He was on the track, trusting that God loved him very much.

When he woke up the next morning, his eyes felt much better. Jason got up and dressed, and when he walked by a mirror, his face looked like itself again. He had passed the test of staying on the track, no matter what, just like Tootle.
