Bible is a mixture of truth and untruth. (Jeremiah 7:22; 8:8; Act 20:28-30) Everything that falls in harmony with our experience is truth. For example, every action has equal and opposite reaction. (Galatians 6:7) This principle works like death which is sure to occur yet we do not know WHEN, WHERE and HOW! This principle is something God too respects hence will not violate at any circumstances as His very highlight is “order.” (Romans 16:20; 1 Corinthians 14:33)
Hence all incidents and concepts contrary to Galatians 6:7, found in the Bible, are interpolations. To mention a few:
1) David is given mild punishment for adultery and murder where as a man who went to gather firewood on Sabbath is given death penalty. (Numbers 15:32-36) (Such a harsh punishment doesn't seem necessary as Jesus declared: “The Sabbath was made for man, and not man for the Sabbath.” - Mark 2:23-27)
2) Once come into power, one can become arrogant like King Solomon and can take 100s of wives and concubines …. who is praised in the later writings!
3) Satan accused Job FOR NO REASON, and thus brought untold sufferings on him only to prove himself a liar and sadist—yet after all the drama Satan was left unpunished!
4) Through one man all became sinners and through another man all would be forgiven! (God forgives only sins committed unknowingly, not other sins—Hebrews 10:26)
Not realizing the interpolations, JWs built their empire on sand. Bible’s interpolated accounts made them audacious to formulate teachings even when they know it is false. For example, their teaching about the year 1914. They know that Jews should know more correctly than anyone else the year of their own captivity. Jewish Ecyclopedia says it happened in 586 BCE. (http://www.jewishencyclopedia.com/articles/11407-nebuchadnezzar) Hence 586 + 2520 = 1935 CE! Yet JWs wanted a wrong date 607 BCE to link the start of Last Days to a spectacular year (607 BCE + 2520 = 1914 CE). However, Jesus himself contradicts JWs here: “When you see Jerusalem being surrounded by armies” (which happened during 66-70 CE), and …. “Jerusalem will be trampled on by the Gentiles until the times of the Gentiles are fulfilled.” (Luke 21:20-24) They say Gentile Times are of 2520 years, and ended in 1914 CE. Yet none of their flock asks: Isn’t 70 + 2520 years = 2590 CE?
This explains why JWs have got most of their teachings unacceptable to the thinking minds!
