Analogy of Jesus Christ - Salt & Light

In Matthew chapter 5 Jesus says that you are the Salt and Light.
Jesus says this just after the BEATITUDES, he emphasises us to know that we are very much important for his kingdom and also to the world which we live. We ought to make certain thing in order to get such blessings. We have to be aware of what we are in him. We should never lose or ignore our gifts, we should alway use it for the right purpose. We should be like examples to the world which does not know about the kingdom of God.

Believers Are Salt and Light

13 “You are the salt of the earth; but if the salt loses its flavor, how shall it be seasoned? It is then good for nothing but to be thrown out and trampled underfoot by men.

14 “You are the light of the world. A city that is set on a hill cannot be hidden. 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. 16 Let your light so shine before men, that they may see your good works and glorify your Father in heaven.

The analogy here is comparing the value of a substance and its unproductive character if it lose its original quality, God recognises that each of us have been given an opportunity, as Jesus says "You are the salt of the earth". There is nothing more than that required for us to be affirmed. Jesus then reassures us that its not just our worthiness enough for us to keep it safe it should be shared with those who have misused their value of life, or who doesn't know their worthiness or value for life. 

Jesus analyses the worthiness:

Each and everyone are valuable in the eyes of God, he never put anyone or any circumstances just like that. Each and every moment of our live is very important for the kingdom. As Jesus says “You are the salt of the earth - by saying this Jesus brings us to a substance which is considered very much useful. Then he says, but if the salt loses its flavor, how shall it be seasoned? It is then good for nothing but to be thrown out and trampled underfoot by men. - Jesus here says but if the salt loses its flavor, that means there are possibilities for that valuable thing to go unused or underutilized. We should never let go of opportunities in life. We should never underestimate one's strength in God, their belief system, We should never compare ourselves with others. We should always go according to the will of the God for our life. 

Jesus says works of the gifts:

Jesus gives us such an importance of our life when he says, " “You are the light of the world." God in the process of creation itself divided the light from darkness. He opposed the darkness, because that which is against the will of God. Darkness represents the forces that limit and condemn, a spirit of infirmity, that which puts limitations. But when we are in light, as Jesus says it cannot be stopped. A city that is set on a hill cannot be hidden. Jesus here asks us to be wise and to have wisdom to discern the time. To be ready for his second coming and to be blameless and to be worthy of his calling. He also says that we should be able to do exceeding things, we are to be examples. Jesus says 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. Which emphasises that the work that one does with his gift tells us about his character. Jesus says nobody will waste their life, with wise and wisdom from God - one will always utilise the things optimistically. 

Jesus gives us an opportunity:

Let your light so shine before men, that they may see your good works and glorify your Father in heaven.

When Jesus says Let your light so shine before men. He says personally to each and everyone. Just after saying nor do they - Jesus says Let your. Jesus again and again emphasis about our utilization of resources to the utmost possible ways, and Jesus says that this will fulfill the most important aspect of our life - 

that they may see your good works and glorify your Father in heaven.

By saying you are the Salt and Light of the earth and world. Jesus gives us utmost care and comfort to make sure that we utilize our time to the fullest and that is not enough, our work has to be so good that the people who never saw God, will come to know about him through our being through Christ.
