Through an enormous amount of study and elaborate experiments, Thomas Edison successfully invented a practical and inexpensive light bulb and demonstrated it on December 31, 1879, at his laboratory in New Jersey – a Herculean achievement that had challenged scientists for over 50 years.  Edison’s first light bulb burned for approximately two hours. After the patent was granted, he and his team discovered a carbonized bamboo filament that would last 1200 hours.  When asked about his previous failures, he said, “I have not failed. I’ve just found 10,000 ways that won’t work. The light bulb was an invention with 1,000 steps.”

Why would someone dedicate so much time and focus to an invention?  For one thing, Thomas Edison was hard-working and not prone to giving up; but primarily, he saw the tremendous benefit of light and the need for it. Today we flip a switch and voilà, we light homes, buildings and streets.  Of course, technology has advanced to develop other modern light sources which only proves the incredible importance of light as an integral and indispensable part of our every day life.

Bible Reading

Think about the difference between light and darkness.  Light helps us see.  It keeps us from stumbling.  Light can lead us through darkness. Even a small amount of light gives us direction.  Light  keeps us on the path.  Light dispels darkness; however, darkness cannot overcome light. Light gives us colors and beauty! Light changes the way we live!

Jesus said, I am the light of the world.  John 8:12


  1. What would it be like to live in darkness or to be totally blind and not be able to see?
  2. What does the light of the sun provide physically?
  3. What do you think Jesus meant when he said, “I am the light of the world”?
