Taste: Salt is not really a pleasant taste on its own but is strong so will get the point across! Simply put a salt shaker on a table and ask people to put a little in their hand and taste it whist they read a scripture referring to salt… Simple! Here are some passages that you could use:

Luke 14:33-35

In the same way, any of you who does not give up everything he has cannot be my disciple.

34″Salt is good, but if it loses its saltiness, how can it be made salty again? 35It is fit neither for the soil nor for the manure pile; it is thrown out.
“He who has ears to hear, let him hear.”

Colossians 4:5-6

5Be wise in the way you act toward outsiders; make the most of every opportunity. 6Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.
