The Characteristics of Light - providing

Direction: Specific to the Source and

Functions as Illumination

Intensity: Measured in brilliance and power

Selective intentional impact

Source of energy (Photosynthesis)

Color: Enhancement and Beauty

Encouraging or Influencing an Emotional Response

Contrast: Distinguishing light from darkness and

revealing that which is hidden


The “Light of the World”

God is Light (1 John 1:5)

He is the source of illumination

Jesus is the Light of the world (John 8:12, 9:5)

He is God in the flesh

We are the light of the world (Matthew 5:14)

We are made lights to the world by God’s

indwelling Spirit


Those indwelt by God who illuminate the world

through the revelation of His love and truth

have become the “light of the world.”


Tasteless Salt & Hidden Lights are WORTHLESS

“You are the salt of the earth; but if the salt

has become tasteless, how can it be made salty

again? It is no longer good for anything, except

to be thrown out and trampled under foot by

men. 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.” (vs. 13-15)


The Metaphor Message

Jesus was telling his disciples that He

EXPECTED THEM to IMPACT and

ILLUMINATE the world around them.


The Application

Let your light shine (Illumination)

that they may see your good works

and glorify your Father (Impact)
