The book called the Bible is the only place to learn about God and His purpose with the Earth. It contains two parts called the Old and New Testaments.
It contains great advice for daily living, and also explains God’s future plan, how He will make it happen, and how we can be part of it. (2 Timothy 3:16)
It is the “inspired” word of God, which means that although it was physically written by men, they wrote under God’s influence, so that the book was a product of His mind, “according to”, “consistent with”, “outlining” or “in accordance with” His purpose. (2 Peter 1:20-21)
