Psalm 12 is about human speech, as used by lying men and as employed by God in biblical revelation. It is about words' use and abuse. The principle involved is that the higher or finer a thing is, the more vulnerable it is to perversion. Love is the greatest quality in life. Yet love can be terribly abused. So also with words. In the lips of an Abraham Lincoln or a Winston Churchill words can inspire and challenge. They can lift a people to days of extraordinary greatness. But in the mouth of a Hitler, equally gifted in the use of speech, they can sweep the world into the destructive wars. Words are both our glory and our shame. 

We ask the question, "If sensible people like that, who had seen Christ die, and who had no anticipation of a resurrection whatsoever, came to believe in the resurrection, as they most certainly did, what is it that convinced them of the resurrection?" There is only one answer. It was the resurrection itself. Christ really rose. They weren't prepared to believe it. They didn't anticipate it. They wouldn't have invented it, but He arose. He surprised them. He came and they saw Him and there was no denying the fact that He was there. Because they knew that was true, they went out from that place with a gospel that literally transformed the world.
