Salt of the Sky
If there were no salt in the oceans, there'd be no rain. The salt goes up to the clouds with evaporated sea water, where it helps facilitate raindrop formation.
I consider, then, Jesus' discussion of how we should be the salt of the earth.
Just as the rain would not fall without the salt of the sky, quenching thirst and giving growth, we will not refresh and nourish others if we "lose our saltiness" on the earth.
Oh, Lord, let me be good salt.
You are the salt of the earth; but if salt has lost its taste, how can its saltiness be restored? It is no longer good for anything, but is thrown out and trampled underfoot. Matthew 5:13
