Summary: “‘If you can’?” said Jesus. “Everything is possible for one who believes.”
“In college I was asked to prepare a lesson to teach my speech class. We were to be graded on our creativity and ability to drive home a point in a memorable way. The title of my talk was, "The Law of the Pendulum." I spent 20 minutes carefully teaching the physical principle that governs a swinging pendulum. The law of the pendulum is: A pendulum can never return to a point higher than the point from which it was released. Because of friction and gravity, when the pendulum returns, it will fall short of its original release point. Each time it swings it makes less and less of an arc, until finally it is at rest. This point of rest is called the state of equilibrium, where all forces acting on the pendulum are equal.
I attached a 3-foot string to a child's toy top and secured it to the top of the blackboard with a thumbtack. I pulled the top to one side and made a mark on the blackboard where I let it go. Each time it swung back I made a new mark. It took less than a minute for the top to complete its swinging and come to rest. When I finished the demonstration, the markings on the blackboard proved my thesis.
I then asked how many people in the room BELIEVED the law of the pendulum was true. All of my classmates raised their hands, so did the teacher. He started to walk to the front of the room thinking the class was over. In reality it had just begun. Hanging from the steel ceiling beams in the middle of the room was a large, crude but functional pendulum (250 pounds of metal weights tied to four strands of 500-pound test parachute cord.). I invited the instructor to climb up on a table and sit in a chair with the back of his head against a cement wall. Then I brought the 250 pounds of metal up to his nose. Holding the huge pendulum just a fraction of an inch from his face, I once again explained the law of the pendulum he had applauded only moments before, "If the law of the pendulum is true, then when I release this mass of metal, it will swing across the room and return short of the release point. Your nose will be in no danger."
After that final restatement of this law, I looked him in the eye and asked, "Sir, do you believe this law is true?" There was a long pause. Huge beads of sweat formed on his upper lip and then weakly he nodded and whispered, "Yes." I released the pendulum. It made a swishing sound as it arced across the room. At the far end of its swing, it paused momentarily and started back. I never saw a man move so fast in my life. He literally dived from the table. Deftly stepping around the still-swinging pendulum, I asked the class, "Does he believe in the law of the pendulum?" The students unanimously answered, "NO!"

We can say we have faith as much as we want. But we really find out about the kind of faith we have when trouble strikes, when we have to actually put it into action. Like the pendulum swinging from side to side, the man didn’t believe as much as he thought when his own nose was in danger.
What about us, when we face persecution or when we go through trials? Will our faith stand the test? That is the challenge. And I hope and pray we all would stand the test in the face of difficult circumstances.
After the three disciples Peter, James, and John experienced the great mountain top experience of seeing Jesus glowing with the power and glory of God, they return from the mountain and immediately they find themselves in a new situation.
It says in Mark 9:14-15: “When they came to the other disciples, they saw a large crowd around them and the teachers of the law arguing with them. 15 As soon as all the people saw Jesus, they were overwhelmed with wonder and ran to greet him.”
They find the other 9 disciples arguing with a group of Pharisees, and around them is a large crowd observing the whole thing.
In verses 16-18: Jesus asks…
16 “What are you arguing with them about?” he asked.
17 A man in the crowd answered, “Teacher, I brought you my son, who is possessed by a spirit that has robbed him of speech. 18 Whenever it seizes him, it throws him to the ground. He foams at the mouth, gnashes his teeth and becomes rigid. I asked your disciples to drive out the spirit, but they could not.”
