“You are the salt of the earth. But what good is salt if it has lost its flavor? Can you make it salty again? It will be thrown out and trampled underfoot as worthless.
 “You are the light of the world-like a city on a hilltop that cannot be hidden.  No one lights a lamp and then puts it under a basket. Instead, a lamp is placed on a stand, where it gives light to everyone in the house.  In the same way, let your good deeds shine out for all to see, so that everyone will praise your heavenly Father. Matthew 5:13-16 NLT
Verses 13 and 14 and begin with the words ‘you are.’ They do not begin with ‘you will be’ or ‘you might be’ or ‘you should be.’ It is ‘you are.’ This is present tense. This is a present reality. Of course Jesus did not stop with stating the present reality. His words exhorted His listeners to live out the purpose of who they are. Just as the purpose of salt is to add flavor and the purpose of light is to illuminate the darkness, Jesus’ followers had a purpose – to live out their good deeds so that everyone will praise their heavenly Father.
Good deeds are not something we do in order to receive a reward from God or to receive the praise of people. Good deeds are part of who we are when we live out our lives as followers of Jesus Christ. As other people observe our good deeds, as they see us responding to challenges in godly ways, they have an opportunity to taste and see what it is like to follow Christ through the actions of His ambassadors.
A second thought relative to these verses is the use of the word ‘good.’ Clearly, Jesus is the deeds of His followers ought not be ‘evil.’ However, Jesus inclusion of the word ‘good’ also means Jesus is not refering to deeds that are neutral, neither good nor evil. As we live out this day, there will be many opportunities to interact with other people. How might you turn every interaction with another person into a ‘good’ deed? How might your words and actions leave them with the thought and feeling that they were blessed to have interacted with you?
 “You are the salt of the earth. But what good is salt if it has lost its flavor? Can you make it salty again? It will be thrown out and trampled underfoot as worthless.
