Ephesians 4:1-16. The Apostle Paul urged the believers to walk in unity, because there is one Lord, one faith, one baptism and one God, even though there are different spiritual gifts.
Isaiah 53. No other chapter in the Bible has so many prophesies fulfilled in the New Testament. Because of this it had been “proven” that it must have been written and added to the book of Isaiah around 400 A.D. As proof for this was cited that the rabbis used to read Isaiah 53 in synagogues, but after the chapter caused “arguments and great confusion” the rabbis of the 17th century decided that the simplest thing would be to just take that prophecy out of the Haftarah readings in synagogues. (Haftarah consists of selections of the prophets, read after segments of the Torah.) That’s why today when they read Isaiah 52, they stop in the middle of the chapter and the week after jump straight to Isaiah 54. See! That is proof enough that it is a later addition to fit with Christian tradition! Then around 1947 the Dead Sea Scrolls were found by some Arab Bedouins, and in them was a complete scroll of Isaiah and chapter 53 was in it, word for word identical with the Masoretic text! The find was announced in April 1948, right before the formation of the State of Israel. This had many years later a profound impact on me after having swallowed bible critical “truth” for many years. I came to realize that if all the book of Isaiah had been written centuries before the birth of Jesus Christ and has well over 50 fulfilled prophecies, both the book of Isaiah is true, and Jesus Christ, his death, burial and resurrection is true, and that changes things. Read it, think about it, and let it sink in!
