The Bible was written by people who witnessed the events it describes; many were persecuted or martyred but never changed their story.
The word Bible is from a word Biblon which means library, it contains 66 books written over 1,500 years by 40 different writers but it tells one “big story” of God’s plan of salvation that culminated in Jesus Christ.
The Bible has a tremendous amount of historical detail: some history books include Genesis, Judges, Samuel, Kings, Mark, Acts, etc. You also find poetry books like Job; you find romance in books like Ruth, Song of Solomon; You find prophesy in books like Isaiah, Daniel, Revelation.
You will find it to be the most unusual and spectacular experience in reading any book. God wants to speak to you, remember this as you open your bible and see what happens.
Here is a nice description I read about the Bible:
“The Bible contains the mind of God, the state of man, the way of salvation, the doom of sinners, and the happiness of believers. Its doctrines are holy, its precepts are binding, its histories are true, and its decisions immutable. Read it to be wise, believe it to be safe, and practice it to be holy. It contains light to direct you, food to support you, and comfort to cheer you. It is the traveler’s map, the pilgrim’s staff, the pilot’s compass, the soldier’s sword, and the Christian’s charter. Here paradise is restored, Heaven opened, and the gates of hell disclosed.
Christ is its grand subject, our good the design, and the glory of God its end. It should fill the memory, rule the heart, and guide the feet. Read it slowly, frequently, and prayerfully. It is a mine of wealth, a paradise of glory, and a river of pleasure. It is given you in life, will be opened at the judgment, and be remembered forever. It involves the highest responsibility, will reward the greatest labor, and will condemn all who trifle with its sacred contents.” Introduction to the Gideons’ Bible
