I know of no better way to open a discussion on lying than to talk about Jesus, who said that He is the "Truth" (and the "way", and the "life", John 14:6). Such an assertive statement was bound to draw the ire of anyone listening assuming their heart wasn't resonant with His. And the effects of said statement continue to reverberate down through the millennia. One current opinion on truth is that we forge our own, that it's subjective. When, in our society, an individual does whatever he or she feels is right—for that reason alone, whether they're Christian or not—they are like driftwood in an open sea. Without the appeal to, or at least acknowledgement of, a superior standard of Truth, said individual has no basis for defending their position (I'm reminded of this: "don't rely on your own insight, in all your ways acknowledge God." See Proverbs 3:5-6). And this—The Way of Lying, if I may—is the default state of every human being who ever lived. Except one: Jesus Christ.
"For God sent not His Son into the world to condemn the world; but that the world through Him might be saved." (John 3:17)
I would like to say that the point of Jesus' first visit to this earth was not to condemn anyone and not to present Himself as some unattainable moral standard. Jesus came to remove from us the Way of Lying that was part of humanity's curse and replace this inherent deadness with His Spirit, The Holy Spirit who is the Spirit of Truth (see John 14:17).
"This is He that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth." (1 John 5:6)
Growing up, even as a Christian, I never really felt that my, uh, comportment—the way I interacted with the world—was genuine, honest, forthright. I'd grown up telling little white lies and hiding things and lying by omission. But as I grew older, into young adulthood, I began to see my childish, childhood decisions bear fruit. I realized, much to my hopeless horror that I'd invested my life in lies and lying.
Things began to change with a simple prayer. I don't remember how long it took for God to show me this answer: "Remove from me the way of lying…" (Psalm 119:29a)
