We all eat and the most important ingredient of what we eat is salt be it small quantity and normally we are not comfortable eating bland and tasteless food.
We also notice that a house that is always dark, there are no activities going on there meaning that light brings about and existence activities remember the very first and important thing God created when he made the world was light he separated darkness from light and during the light time activities are supposed to go on meanwhile during the dark time everything stops.
Now lets also take a look at this , imagine people born into royalty or lets use the whole royal household, they i actually entitled to every thing in the kingdom, the can go anywhere, do anything in fact the have the the final say.they are being respected by their subject and so on.
We as Christians we are likened to the salt of the earth because we are supposed to add taste to everything around us,a add taste to people's life. We are also light because wherever there is light darkness flees , whatever we do we are meant to be outstanding, we are meant to shine and illuminate others around. we are royalty born into the kingdom of God royal priesthood, peculiar people yunno. we have rights and dominion on the earth
so we should live right, be morally upright, and portray these entitlements above given to us.
