Read Matthew 5:13
13 “You are the salt of the earth. But what good is salt if it has lost its flavour? Can you make it salty again? It will be thrown out and trampled underfoot as worthless. (NLT)
Salt has two functions. One is to add flavour; the other is to prevent decay and rot. Jesus wants his followers to add flavour and taste to the world and also to be preservatives to stop the world getting worse than it is.
If at social gatherings you mention you are a Christian, something like a wet blanket may descend on the conversation. People see Christians as moralistic bores who frown at anything remotely enjoyable. Jesus didn’t seem to fit that description and nor should his disciples. Any social gathering or group should be enlivened by the fact we are in it.
That doesn’t mean we just go along with prevailing ideas in order to win popularity. We also seek to make the world a better place by speaking and acting against all that would dehumanise and destroy. Which means we will have opposition. Not everyone will appreciate our flavour and not everyone will want to see the world a better place.
If we lose our distinctiveness, we are not much good to anyone. Christians who lack taste and flavour, or who don’t seek to preserve the good in the world, are not being true to their destiny. We are to be neither timid compromisers nor bigoted eccentrics. We are to be different, yet positively different. A bit like Jesus actually.
