Yes we can trust the Bible as it is written today. The Bible itself is special, different from all other books, in two ways: its *construction*, and its *content*.
The Bible is a set of stories, written by many (about 40) authors, over a long time (over 1000 years). And it all agrees with itself -- newer stories refer back to old ones, and they don't contradict each other. There are more ancient copies of the Bible, that have been carefully scrutinized, than any other ancient text in written history. And, the number of differences found between all those texts, from oldest to newest, is very tiny (the number is less than 10% unless my memory fails me). This is a miracle, considering all those authors, all those copies, all by hand, over all those years.
That covers the *construction* of the Bible. The *content* is a whole other world, and it's impossible to give it justice in a single paragraph. The most important points are these:
- God is real, and he designed and created the world we see.
- God wants to be close to his creation. He loves all of it, especially the people in it.
- People are made with free will, because love is only meaningful if we choose to give it, and to commit to it.
- People who choose to not love God, and to not believe God, are given many chances to return to his side.
- God proved his own love by sacrificing himself for all people who don't love him.
- Someday there will be too many people far from God's side, then his patience must end and his wrath will be revealed.
The Bible is a complete history of this age of human life on Earth, from its very beginning to today, to the next age where God will restore Earth after too many people have abused their free will. No other books from any other religions encompass so much, so completely, so coherently.
