We cannot be the “salt of the earth” if we separate ourselves from the decay.
In warm climates, salt did much more than flavour the food. It was a natural preservative. This raises the question as Jesus uses it to describe his Kingdom: did Jesus come to preserve traditions or morals, or is it something else?
Salt needs to be connected with the thing it’s preserving. Could it be that we are to get involved in the mess and dirt of this world in order to be effective?
Also, salt should enhance the flavour – not overpower it. Is our job to enrich what God has presented to us, rather than replace it?
