Jesus takes simple everyday things to help us understand how we are to be disciples.
When salt loses its taste, it is of course of no use. We as disciples need to be true to ourselves and authentic if we are to be effective and make a difference. We are to be salt of the earth. By being the person God created us to be we can make a difference, for the good, to others and to the wider world.
When I was young, I spent many happy holidays in the shadow of the Malvern hills. During the day looking at them they were a wonderful array of greens and gold but once night fell throughout the side of the hill you saw pin pricks of light, coming from the houses on the hill side. I was able to see where people lived. We are light that shines in the darkness of our world that give others joy. It is important to note the words that Jesus says, “Your light must shine before people so that they may see your good works and give praise to your father in heaven.”
There is a temptation to do good things so that people will look at us and say. “What a wonderful person you are”. Doing good so that people will notice us is not what is called for. We need the grace to do acts of love so that God is given the credit. We pray that what we do will give others a glimpse of God.
