The Bible was written by men inspired by God. It contains 66 "books" (like chapters) written by about 40 men over a period of about 1400 years. It contains an accurate history of what God has done, will do, and commanded us to do. We have 1,000's of ancient manuscripts of it.
The 1940's discovery of the Dead Sea scrolls was a gold mine. It included a nearly complete copy of the book of Isaiah. This copy was dated to 125 B.C. (before Jesus). Isaiah is the sixth longest of 66 books in the Bible. There are no significant differences between its text and more recent copies. Those who claim the Bible has been changed are incorrect.
Isaiah gives us many predictions of the future. Chapter 53 has repeated specific prophecies of one who would come and die for our sins and live again. (That is Jesus!)
There are many different translations of the original texts into English. Some translations take more liberty in paraphrasing than others. And some minor differences in the original texts. A good study Bible, such as many New King James bibles, gives the alternate readings if source texts differ. But these differences are minor and in no way change the message of the Bible.
The Bible includes both miracles and prophecies, historical events verified by archeology, how men obeyed or disobeyed God, and the consequences. It is not a self serving book. Though the authors are all Jewish, except one (Luke), it often describes when the Jews disobeyed God, and less often when they did well. It predicted the Jews would be scattered to all the nations of the earth, persecuted, and return to Israel in the last days before Jesus returns. Historically, the Jews were scattered in 70 A.D. when they rebelled against the Romans and only got their land back in 1948. After World War II, when Hitler tried to exterminate all Jews, killing 6 million, the United Nations gave them part of their historic homeland. In May 1948, when they proclaimed nationhood, they were immediately attacked by the surrounding five Arab (muslim) nations. The U.N. had offered a two state solution. The Jews accepted that, but the Arabs rejected that. What is going on in Israel now is fulfilling Bible prophecy. There will fighting over Jerusalem, just at the Bible prophesies - see Zechariah chapter 12.
No other book remotely compares with the Bible's over 1,000 predictions of the future. That is one way we know it is inspired by God. Sadly, one of Jesus' predictions is that many people will falsely represent Him. Fake Christians. Many deceived churches. The Bible says in the last days (now), just before the coming judgment of a sinful world, many Christians will fall away from the truth. In the US there has been an ongoing falling away from God in the last 70 years. Who would make predictions about his followers like that? Jesus did. Remarkable, accurate, sad, but true.
The Bible predicts the future, including your future. Eternal life if you please your Creator with a holy life lived by faith in Him, eternal damnation if you reject/ignore Him.
