You serve as the light of the world through your good works. When you light up your world, people will bask in your light and glorify your father in heaven. There should be something about you that influences an aspect of society in a positive way. You need to stop thinking about “light up the world” as a spiritual affair. This is not some vague light or some internal, spiritual bliss you enjoy. Jesus was being quite explicit when he explained that you are meant to be the kind of light that is not hidden (Matthew 5:14 – 16).
In the real sense of it, darkness is not the opposite of light. Scientists do not measure darkness, there is no physical quantity that expresses darkness. As far as we can tell, darkness is the absence of light. So, the darkness in your world is due to the absence of good people to light it up with good works. Think about how dark and bleak your world would be if certain people did take up the responsibility of lighting it up. You have people working round the clock to solve problems that are not even their concern. There are many problems in your world today, and someone (that’s you, by the way), must step up and decide they will shine brighter than the darkness.
Arise, shine, for your light has come, and the glory of the Lord has risen upon you. For behold, darkness shall cover the earth, and thick darkness the peoples; but the Lord will arise upon you, and his glory will be seen upon you. And nations shall come to your light, and kings to the brightness of your rising (Isaiah 60:1-3 ESV). It is time for a fresh approach to life. The idea that there is a lot of good you could do that makes a positive difference in society. If you do not do this good you could do, there will be darkness. If you do the good you could do, “His glory” will be seen upon you. Benjamin Franklin asked himself two questions each day. In the morning, he asked, “What good shall I do this day?” At the end he asked “What good have I done today?”
