You are the salt of the earth; but if the salt has become tasteless, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled under foot by men.
You are the light of the world. A city set on a hill cannot be hidden; nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house. Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven. (Matthew 5:13-16, NASB)
Part of a Christian's identity is being salt and light. Being salt and light is not optional. It's a way of saying that our actions should show what we believe---so much so, that others are drawn to the Lord.
During recent travels, I witnessed 2 shops, one in Sand Rock, AL and one in Dahlonega, GA that not only sold gifts, but also provided salt and light for their community through a prayer wall. Prayers needed. Prayers answered. Posted for all to see---even out-of-towners.
"Salt" and "Light" in a gift shop to draw others in their community to the Lord.
All of our lives should be so "sal-TEA" that others become thirsty and desire to sip from whatever our cuppa holds. Living water.
