After speaking about the blessing that belongs to those who belong to His ‘upside-down’ Kingdom in the Beatitudes, in Matthew 5:13, Jesus then spoke of the influence that He expected His people would have on the world, by being ‘salt’ in an often tasteless world. Why did Jesus describe believers as being like salt? Because of the way in which salt was highly valued in Jesus’ day, because of the way in which salt was also used as a preservative, the way in which salt creates thirst, and also the way in which salt could so easily lose its flavour and become useless. For all these reasons believers are to be in the world and so have a preserving, thirst-creating and godly influence on others and therefore on the world.
