“If the foundations be destroyed, what can the righteous do?”
The most effective way to destroy the truth is to redefine the words used to teach the truth. How can one teach the truth about salvation if the word “salvation” has been redefined? In that case, you are saying one thing, but the listener is hearing something else. You cannot communicate the truth to someone who does not understand your words.
Satan has redefined many of the words we need to use to explain the truth. He cannot keep God from revealing truth, for God speaks to the heart. But between humans, Satan has erected crafty barriers of communication, the most effective barrier being the redefining of words used in the Bible to tell the story of Jesus.
