Jesus Died and Rose Again
Electricity: Power for life
What happens when you turn on a light switch? The room lights up, of course. But have you ever wondered why? The secret is electrical power.
It all begins with atoms. Everything is made up of atoms — this magazine, the food you ate for breakfast, your dog — even you. Atoms are much too small to see. They’re so tiny it would take a million of them to stretch across the width of one of your hairs! But atoms can create a lot of power. Atoms contain electrons. Sometimes electrons move from one atom to another. These traveling electrons create an electrical charge. This is electricity.
Some materials allow electrons to travel more easily than others. We say these materials are good conductors of electricity. Electrical cords often contain copper wire. Copper is a good conductor. Rubber and plastic are poor conductors. We call things like that “insulators.” Electrical wires are often wrapped in rubber so the electrons don’t travel to us and shock us.
When you turn on a light switch, a plastic lever pushes together two pieces of metal so they touch. That allows electricity to flow toward the light bulbs. A wire in each bulb quickly heats up and glows, and light fills the room. It happens so fast you barely even notice it. That’s the amazing power of electricity.
We can see electricity at work when it storms. Lightning happens when electrons move from one place to another. Sometimes the electrical current travels from cloud to cloud. Other times it moves from a cloud to something near the ground. Lightning is powerful and dangerous. Always head indoors when you see it.
Few things in our world are more powerful than electricity. It provides us with light, runs our vacuum cleaners and televisions, and even powers some trains and vehicles. But it can’t bring anyone out of the grave.
Jesus died on the cross to take the punishment for our sins. (You can read more about that on page 20.) Jesus’ friends were sad when He died. They placed His body in a tomb. But after three days, a miracle happened. Jesus rose from the dead!
God is powerful enough to overcome sin and death. The same power that raised Jesus from the grave can change our hearts and give us life that never ends.
