The main idea of what this book gives out is that you are saved by grace through faith. Because faith comes from hearing, hearing by the word of Christ (Romans 10:17). Your works or merits will not get you saved, because it is not sufficient enough to pay the eternal hell punishment that you deserve. Everyone in this world is born into sin, and you have the decision to live your life without a savior who will be willing to take your eternal hell punishment for you or accept Jesus Christ as your savior who died on the cross for your sins and rose from the dead on the third day. Every part of Scripture in the Bible is considered infallible and perfect. There are no contradictions or errors within the Bible, which has 66 books. This book can be used to study and memorize parts of Scripture. And use it as part of your prayers so that you can apply the word of God to your life.
