Dr. David Jeramiah said:
"Salt is a preservative, but it also creates thirst. Ranchers often give their cattle blocks of salt to lick so they will drink more water. That is a picture of our purpose as salt in the world, to make the spiritual thirst of people around us so strong that they reach out for the living water which Christ offers. The reason to emphasize Christlikeness is, first of all, out of obedience to God. But when we do that, we so distinguish ourselves from the world that their thirst for living water becomes stronger when they see our life. The reason people come to Christ is that they are thirsty and discover the He is living water."
