Dr. Elizabeth Mitchell says...
April Fool's Day is here, and while it is not a national holiday, many people around the world celebrate the day with practical jokes. The bounds of social pressure confine most tricks to the good-natured and harmless, and most of us use the day to innocently have a good time with our friends. Nevertheless, the time seems right to briefly explore the subject of foolery and lies.
History and literature offer a number of tidbits relating to the day, with Chaucer's "The Nun's Priest's Tale" Canterbury Tales being a fourteenth-century contributor. Int the tale, Chaucer - the first man to eventually be buried in the Westminster Abbey's Poets' Corner - retells the fable of "Chaunticleer and the Fox" set on March 32 - which of course is the first of April. The tale involves not just falling for a lie but doing so due to pride - a lesson that should make us pause to think about every gullible person from Eve to the one in the mirror.
God hates lying. Why? The serpent's deception of Eve led to mankind's rebellion, which brought a curse upon the world God created. The result was untold suffering to those He had made in His image. The serpent deceived Eve into doubting God's goodness and then lied as he accused God of being a liar. Man was made in God's image. God cannot lie (Num. 23:19). Therefore, man was designed to be truthful, not deceptive.
