Let your words always be with grace. Let them be seasoned with salt

Food with salt is a metaphor for words that teach others and that others enjoy hearing. Alternate translation: "Let your conversation always be gracious and attractive" (See: rc://en/ta/man/translate/figs-metaphor)

so that you may know how you should answer

"so that you may know how to answer questions from anyone about Jesus Christ" or "so that you may be able to treat every person well"
