Salt and Light

What are the inherent properties of salt and light that Christians need to demonstrate? What did salt and light mean in Christ’s days? What do we learn? How do we achieve inherent characteristics that have the power and influence salt and light have?


Ref: Matt 5: 13-16 Mark 9.49-50; 4.21; Luke 14.34-35; 8.16








  • Describe the responsibility of a true disciple
  • Know the consequences of losing our property/quality
  • Understand that our true calling is to reveal God to the otherwise dying world

Mt.5:13  “You are the salt of the earth. But if   the salt loses its saltiness, how can it   be made salty again? It is no longer   good for anything, except to be   thrown out and trampled by men”.

You are the Salt of the Earth


  • Purifies and cleanses
  • Preserves
  • Seasons
  • Seals covenant
  • Was money
  • Creates thirst

Salt Purifies and Cleanses

Elisha’s purifying of the waters of Jericho by using salt symbolises the power of God through purifying property of salt.

2 Ki.2:21 “… he went out to the spring and threw the salt into it, saying, “This is what the LORD says : ‘I have healed this water;…”

Salt Preserves

Prevents decay by delaying putrefaction whereas yeast promotes it.

Exo. 30:35 “… and make a fragrant blend of incense, the work of a perfumer. It is to be salted and pure and sacred”.


    Salt Seasons

    Salt has the ability to give flavour to that which is otherwise bland

    Col.4:5-6  “…Let your conservation be always full of grace, seasoned with salt, so that you may know how to answer everyone.”

    Covenant of Salt

    A permanent agreement between God and His people.

    “My tumhara namak kaya” (I have eaten your salt)…covenant is enduring relationship after sharing a meal.

    2 Chronicles 13:5 “… Don’t you know that the Lord, God of Israel, has given the kingship of Israel to David and his descendants forever by a covenant of salt?”


    Salt was money

    Salt was in fact a form of money/ wages in those days. That is where the term “you are worth your salt” came from.

    Salt creates thirst

     “A salty Christian makes others thirsty for Jesus, the water of life.”

    If the salt loses its saltiness

    Lk.14:34-35 “Salt is good, but if it loses its saltiness,  how can it be made salty again ? It is fit neither for the soil nor for the manure pile; it is thrown out. He who has ears to hear, let him hear.”

    When we abandon our purpose, we are good for nothing.


    Light - Key Verses

    Mt.5:16  “In the same way, let your light   shine before others, that they may see   your good deeds and glorify your   Father in heaven.”

    Matthew 5:14 “You are the light of the world. A city that is set on a hill cannot be hidden.”

    A city set on a hill cannot be hid - context

    Roman cities were typically on hills.  The lights/ torches on walls gave warning signals:

    • 2 torches – enemy sighted
    • Torch on North and West wall – do not delay
    • Torch on East, West and North – we are being attacked – last warning
    • Torch on 4 walls – gates closed, under seige
    • Torch extinguished – city fallen


    You are the light of the world

    Matthew 5:15 Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house.

    In the context of warning lights (v 14), how can we put our light under the bushel?



    • Exposes darkness
    • Expels darkness
    • Establishes direction

    Philippians 2:15  “… become blameless and pure, children of God without fault in a midst of a crooked and perverse generation, among whom you shine as lights in the world,”



      Light Exposes darkness

      The sin and evil of the world is revealed in the light 

      John 3:20  “Everyone who does evil hates light, and will not come into the light for fear that his deeds will be exposed”

      Light Expels Darkness

      When we reflect the light of Christ we dispel the spiritual darkness around us.

      2 Corinthians 4:6  “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.”

      Light Establishes Direction

      Amidst the dangers of the world we can walk safely in His light.

      John 11:10  “It is when a person walks by night that he stumbles, for he has no light.”

      We can give out light only because we have received light.

      Ephesians 5:8  “For you were once darkness, but now you are light in the Lord. Live as children of light”

      light of the world

      The Source

      John 8:12 …Jesus spoke again to the people, he said, “I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.”

      The Recipient

      1 Thessalonians 5:5 … You are all children of the light and children of the day…

      let your light so shine

      Our light is not meant to be hidden but to reveal who we are in Him.

      Eph.5:9-10  “(for the fruit of light consists of all goodness, righteousness and truth) and find out what pleases the Lord.”

      1Pet.2:12  “Live such good lives among the pagans that, though they accuse you of doing wrong, they may see your good deeds and glorify God on the day He visits us”
