The Bible says, if you can master the tongue, you can master your whole body.
However, words can be weapons, and when someone becomes an expert at using them, they can get us to believe almost anything… PARTICULARLY, if we are not SOLIDLY grounded in THE TRUTH.
The Bible says that in the end times, good will be called evil, and evil, good. And this is going to be accomplished, largely, by words being crafted in a way that makes us comfortable with dark ideas, and allows us to grow at peace with some of our darker impulses.
“Expert” liars become skilled at playing in the margins, working in the “GRAYS,” using mostly the truth, to get us to swallow the desired lie.
The entire story of man’s fall, his condemnation to a life that ends in death, and the ultimate suffering of humanity, comes down to this EXACT principle.
