What Light Reveals


This year, God made it obvious to me that I was to home-school our oldest son.  Homeschooling him has been a time commitment and definitely keeps me busy, which is why you may have noticed the reduction in the number of recent blog posts written by me.

One of the things I really love about teaching my son is all the things I learn right alongside him.

This week, we began the chapter on the study of light in his science book.  As I was reading and discussing the characteristics of light with my son, so many spiritual truths began to speak to my heart as well.

I wanted to share some of the characteristics of light with you and hope that in the process, you are blessed just as I was/am.

Note: We are not finished with this study, and my thoughts are not conclusive nor extensive on this matter.  I would encourage you to study the physical aspects of light and then compare them to what Scripture tells us concerning light.

I believe that the physical world/God’s creation was created to reveal many spiritual lessons to us as well.

Jesus says this concerning Himself and light:

John 8:12

12 Then Jesus spoke to them again, saying, “I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.”

As we read through the characteristics of light, let’s keep in mind what Jesus is revealing about Himself and about us, when He tells us that we, as His children, are also lights to the world.

The definition of light is the following:

  • “Light is energy moving through space from its source to an object and then from that object to our eyes.” (taken from ABeka’s 5th grade science book)

Here are some characteristics of light (taken from ABeka’s 5th grade science book):

  • Light always travels in a straight line.
  • Light travels faster than sound — faster than anything else scientists can measure.

There are also descriptions concerning an object’s “response” to light (taken from ABeka’s 5th grade science book):

  • An object is transparent if it allows light to pass straight through it.  Transparent items are clear — nothing hinders the ability of light to pass through them.
  • An opaque object does not allow light to pass through it.  (It also creates shadows when the light hits it.)
  • A translucent object diffuses or scatters the light.  People can see light through them but not objects.  For example, light from the sun passes through the clouds, but the sun was hidden.

More random facts concerning the subject of light (taken from ABeka’s 5th grade science book):

  • The size of the shadow, created by light hitting an opaque object, varies with the position of the sun.  At noon, when the sun’s strength is at its fullest, shadows are smallest.
  • To reflect is to give back the light of the sun.
  • Luminous objects produce their own light.
  • Any material heated to a high temperature will give off light.

Knowing what we know scientifically about light, what does this tell us in regards to the following verse?

Philippians 2:15

15 that you may become blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world,

How does this command challenge us when we examine our own lives in light of His Word?  Are we “transparent,” “translucent”, or “opaque”?

Suffering is often referred to as “heat”.  What might this tell us in reference to how sufferings can allow God’s light to shine more brightly in our own lives?

Isaiah 48:10

10 Behold, I have refined you, but not as silver;
I have tested you in the furnace of affliction.

Zechariah 13:9

I will bring the one–third through the fire,
Will refine them as silver is refined,
And test them as gold is tested.
They will call on My name,
And I will answer them.
I will say, ‘This is My people’;
And each one will say, ‘The Lord is my God.’”


What does the definition of light (“Light is energy moving through space from its source to an object and then from that object to our eyes.”) reveal to us in regards to God when He says the following?  How does this verse show us that God is the Source of all light?

Genesis 1:3

Then God said, “Let there be light”; and there was light.

The following verses give both commands and warnings in regards to either the presence or absence of light and of what causes darkness within us (spiritual darkness):

Romans 13:12

12 The night is far spent, the day is at hand. Therefore let us cast off the works of darkness, and let us put on the armor of light.

1 Corinthians 4:5

Therefore judge nothing before the time, until the Lord comes, who will both bring to light the hidden things of darkness and reveal the counsels of the hearts. Then each one’s praise will come from God.

Matthew 6:22

The Lamp of the Body

22 “The lamp of the body is the eye. If therefore your eye is good, your whole body will be full of light.

Luke 11:35

35 Therefore take heed that the light which is in you is not darkness.

The following verses indicate what light is in the spiritual sense.  Note: God is the Source of light, but what is this light within Him like? (What’s its purpose?)

Acts 26:18

18 to open their eyes, in order to turn them from darkness to light, and from the power of Satan to God, that they may receive forgiveness of sins and an inheritance among those who are sanctified by faith in Me.’

Matthew 4:16

16 The people who sat in darkness have seen a great light,
And upon those who sat in the region and shadow of death
Light has dawned.”[a]

Luke 1:79

79 To give light to those who sit in darkness and the shadow of death,
To guide our feet into the way of peace.”

Luke 2:32

32 A light to bring revelation to the Gentiles,
And the glory of Your people Israel.”

2 Corinthians 4:6

For it is the God who commanded light to shine out of darkness, who has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.

Colossians 1:12

12 giving thanks to the Father who has qualified us to be partakers of the inheritance of the saints in the light.

The above list of verses is definitely not exhaustive.  I would need to publish a book in order to include all the verses in regards to light.

Light reveals truth.  In the physical sense, this is true as well.  When a light is turned on, we can suddenly see the dust on the light-shade and the toys hiding in the corner of the room.

Light benefits us in many ways. In fact without light, life couldn’t and wouldn’t survive for long.

Without light, plants wouldn’t grow.

Without a source of light, there would be no warmth, and the earth would freeze over.

Proper lighting is also important when it comes to photography and art-work.

Light is also important for emotional and mental stability.  In fact, people are known to often be more depressed in the darker, colder months of the year.  Some depression is treated with “light” treatments.

Our physical survival depends upon light.  What does this signify in regards to the importance of our relationship to the Source of light in our spiritual lives?

I have only begun this study and already I feel challenged, encouraged to draw closer to God as my Source of “light”, and amazed to see how God reveals His truths in so many creative ways!

Knowing that one of the characteristics of light is that light travels in a straight line, read the following verse with wonder and also with thanksgiving:

James 1:17

17 Every good gift and every perfect gift is from above, and comes down from the Father of lights, with whom there is no variation or shadow of turning.
