After reading “You are the salt of the earth” (Matthew 5:13), young people at a Bible study were asked to describe “salt.” They couldn’t just say “sodium chloride”; they had to describe the effects and physical reactions of salt.

“It gives food a tang,” one said. Others suggested: “It imparts flavor.” “It preserves from decay.” “It has a purifying action.”

Finally, one young girl said quietly, “Salt creates thirst.”

A convincing hush fell as they thought, “Ye are the salt of the earth” and asked themselves, “Have I ever made anybody thirsty for the Lord Jesus whom I profess?”
