“You are the light of the world. A city set on a hill cannot be hidden; nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house.… (Matthew 5:14-15)
Last week we talked about being the salt of the earth. This week we look at a similar metaphor with the same idea. Not only are we the salt of the earth, but we are also the light of the world. Both give the idea that being a Christian is not just about inward belief but also external influence. Like it or not, as God’s children and members of His family, we represent him in what we do, how we behave and what we say.
To understand the metaphor better, let’s consider what light does.
1. As a signal.
Light can indicate where you are going such as an indicator or a turn signal. When to stop and start, such as in traffic lights and it can also be used in pulses of light from one ship to another to send a message (e.g. Morse code).
2. As a guide.
A very famous verse in the bible is Psalm 119:105 Your word is a lamp to my feet and a light to my path. Light is of course vital if you are travelling at night, or you really will do yourself an injury.
3. To dispel darkness
Darkness cannot occupy the place where light is. Where there is light, there cannot be darkness. Light is used to penetrate the darkness and expose evil and error.
The light shines in the darkness, and the darkness can never extinguish it. (John 1:5 NLT)
And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil. For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed. But whoever does what is true comes to the light, so that it may be clearly seen that his works have been carried out in God. (John 3:19-21)
4. As security
A security light on the outside of a house for instance, comes on whenever anyone is sneaking past, to expose their movements.
Take no part in the unfruitful works of darkness, but instead expose them. For it is shameful even to speak of the things that they do in secret. But when anything is exposed by the light, it becomes visible (Ephesians 5:11-13)
5. To produce growth
Plants grow because of the light (called photosynthesis). You will even see plants turning towards the light to get the most light they can.
6. To bring life
Very few things grow in the dark. In a forest only moss and fungus grows on the forest floor, but in a summer meadow, things grow very quickly. Just ask a gardener who has to constantly mow the lawn.
Jesus is the exclusive and only light. He is the true light.
Again Jesus spoke to them, saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life. (John 8:12)
So if Jesus is the light of the world and He is the only light, why did He call us the light of the world as well?
The answer is that as followers of Jesus we reflect His light. For example the moon has no light of its own, but as it reflects the sun’s light it can light up the night sky. The more time we spend in His presence the brighter we will become.
As Christians we will never cease to have that light within us, but what we can do is hide the light so that others cannot see it. That is what the rest of the verse is about. Jesus is saying it is pointless having a light and then covering it over and yet that is what some of us do.
The basket we cover the light with can be all sorts of things: It could be fear of what others might think, or of losing our respectability. We might not want to offend others and make waves or we just want people to accept us. What is your potential basket? Whatever that basket is we need to deal with it.
Another story about light in the bible was the parable of the 10 virgins in Matthew 25. The five foolish virgins were actually not Christians at all because they did not get into the wedding feast. The oil they should have had represented their lack of a relationship with Jesus. The message is the same though; we need to have our lamps ready, we need to be ready to shine whenever and wherever we are called to.
As I was writing this blog I found myself singing a song I sang a very long time ago in Sunday school “This little light of mine, I’m gonna let it shine” If it’s good enough for the children, it’s good enough for us! What do you think?
