Today's the day when in 1879 inventor Thomas Edison first gave a public demonstration of his incandescent light bulb, by lighting up a whole street in Menlo Park, New Jersey. The Pennsylvania Railroad Company ran special trains to Menlo Park on the day of the demonstration in response to public enthusiasm over the event. Although the first incandescent lamp had been produced 40 years earlier, no inventor had been able to come up with a practical design until Edison embraced the challenge in the late 1870s. After countless tests, he developed a high-resistance carbon-thread filament that burned steadily for hours and an electric generator sophisticated enough to power a large lighting system. Of his many inventions, the electric light bulb remains the one he is best remembered for, and the one that has had the biggest impact on society.
God is the Creator of light itself, one of the most complicated and yet most basic components of the universe. But he is not content just to let us live in physical light. He also switches on the light of his truth in our hearts. When the Spirit of God leads us to understand who Jesus is and put our faith in him, a light really does come on inside. This is how the Bible explains it in 2 Corinthians 4:
For God, who said, "Let light shine out of darkness," made his light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ.
So as we approach a New Year, let's make it our resolution to let God sweep out the darkness in our lives.
