Are we really salt?

Jesus said, "You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people's feet." Matthew 5:13, ESV

Most people of Jesus' time probably thought of salt in terms of its preservative characteristic. As people have studied salt over the years we have learned it is both a preservative and much more.

Royal Society of Chemistry, London, says:

"Why do we need salt? It is the sodium (ions) present in salt that the body requires in order to perform a variety of essential functions. Salt helps maintain the fluid in our blood cells and is used to transmit information in our nerves and muscles. It is also used in the uptake of certain nutrients from our small intestines. The body cannot make salt and so we are reliant on food to ensure that we get the required intake." http://www.rsc.org/get-involved/hot-topics/Salt/do-we-need-salt.asp

If the the world needs feeding with spiritual salt the same way that the human body needs physical salt, what answer comes back when we Christians ask ourselves:

"How does my life, how does the church's life measure up to the Lord's description of us as salt?"

Christ will bury wickedness

He hated wickedness, so much that He bled to wound it to the heart; He died that it might die; He was buried that He might bury it in His tomb; and He rose that He might for ever trample it beneath His feet. Christ is in the Gospel, and that Gospel is opposed to wickedness in every shape.
(Psalm 45:7, Thou hatest wickedness., Spurgeon's Morning & Evening, Morning, May 29)

How should the world behave?

 A thought struck me while reading my morning devotion. As we Christians see the world depart swiftly from what the Bible teaches to be good, are we more concerned that the world is not as nice as we would have it, or that the world seldom glorifies God?
