The Guide to Eternal Life was written to show that the Bible is the inspired word of God. You will see some of the evidences from astronomy, archeology, prophecies, as well as some other examples that point to that truth. Many people say the Bible is just a made-up story and does not have any meaning for us. There are thousands of archeological finds that give evidence to the authenticity of the Bible. The unbelievers' reasoning is to say the examples are coincidences. How many coincidences can you have before you begin to believe that maybe the Bible is God's inspired word.
The rest of the book points out what the Bible says about man's nature, and how that nature affects his eternal destiny. It points out what God has done for humanity and how we can acquire God's gift for ourselves.
Most people I talk to seem to think that believing in God, going to church, and just being a good person will, maybe, get them eternal life with God. The Bible tells us that "these things have I written unto you so you may know you have eternal life." This book tells you what those written things are.
Once you have accepted the Bible as God's word, you only need to find out exactly what it says and accept it.
This book can make the difference where you will spend eternity. Happy reading.
