Hello Andrew,
You may be only 21 years old, but I like the thread you started. Why is there so much falsehood in almost everything we hear and read, because Satan is the Father of the Lie and is the ruler of the World, He offered Jesus all the Kingdoms of this World, if he would fall down and Worship Him. Satan is misleading the whole World. ( John. 8:42-47; Matt. 4:8-10; Rev. 12:9 ). It's God's Will that we are exposed to all this Lying and Deceit in order to eventually learn Truth's, especially Spiritual Truth.
I remember when I was very young, approximately 11 or 12 years old and being extremely honest and naive. I would always tell the truth, even about things that were none of anyone's business or involving information that people weren't entitled to receiving. I would bring embarrassment upon myself, the teacher at school(my favorite one of all time) stated: "Bradley is the most honest boy I ever met."
Why do I include this in my Post, because as I grew older I realized that people ridicule the Truth(not everyone) and it seemed that I would be punished and suffer more from being just plain honest.
Of course, I learned that being honest doesn't mean we have to divulge information to those that aren't entitled to it. As an example: My wife and I read Judges. 13-16 regarding the account about my favorite Old Testament Person, Samson. In the part about his dealings with Delilah, Samson technically lied to Delilah regarding the secret to his great strength, probably to throw her off and also because it was none of her business, eventually he gave in to her persistent nagging and you know the outcome. I said to my wife, if someone wanted to get technical, Samson lied to Delilah twice regarding the secret to his strength. My point is that sometimes people might tell something to another person to throw them off, instead of rudely saying: IT'S NONE OF YOUR BUSINESS. Sad to Say, like Samson of old, occasionally this Samson will succumb to the persistent nagging and pressure eventually giving out personal information that they are not entitled to.
Now I realize that your basically referring to outright lying, half-truths and distorted truth. The worst of it is the partial-truths or distorted truths, because it's easier to mislead people with these, outright lies are more obvious to most of us.
Andrew, you are a young man of 21 years; it's good that your well aware of so much lying and it annoys you, in this way you might be able to unravel these Lies and learn Truth at such a young age. Furthermore, if you've notice so much lying already, as the song goes; BABY, YOU AIN'T SEEN NOTHING YET(Bachman Turner Overdrive).
By the way, in regards to the Carrot thing, it's true that carrots in themselves don't improve your eyesight, but something in the carrots are converted to Beta Carotene( A form of vitamin A) which does.
Yes, Andrew, don't let all this Pathological Lying get to you or you might end up with an ulcer when you get my age(52-almost), it gets frustrating for those of us who would like to get an honest straight answer from people without hearing all this baloney( I preferred another word, but it's not allowed at this Forum).
Lately my employer is the worst liar of all, If your employed you'll eventually experience that, if you haven't already. In their case, they won't even give me an answer to the simplest of questions, but keep avoiding me.
Sorry, if my Post wasn't what you were looking for.
Kind Regards, Samson.
