I will first address why the Bible says that it is the Word of God. If you don't believe in the Bible then I will give you comments on why I believe and know that the Bible is true, and God's Word.
According to the Bible, why is the Bible true?
John 17:17/ "Your word is the truth..."
2 Timothy 3:15-16/ Since childhood, you have known the Holy Scriptures that are able to make you wise enough to have faith in Christ Jesus and be saved. Everything in the Scriptures is God's Word. All of it is useful for teaching and helping people and for correcting them and showing them how to live."
Hebrews 4:12/ "What God has said isn't only alive and active! It is sharper than any double-edged sword. His word can cut through our spirits and souls and through our joints and marrow, until it discovers the desires and thoughts of our hearts."
2 Peter 1:19:21/ "All of this makes us even more certain that what the prophets said is true. So you should pay close attention to their message, as you would to a lamp shining in some dark place. You must keep on paying attention until daylight comes and the morning star rises in your hearts. But you need to realize that no one alone can understand any of the prophecies in the Scriptures. The prophets did not think these things up on their own, but they were guided by the Spirit of God."
Romans 16:25/ "...He can make you strong by means of my good news..."
Romans 7:12/ "Still, the Law and its commands are holy and correct and good."
Romans 7:14/ "We know that the Law is spiritual..."
Romans 2:14-16/ "Some people naturally obey the Law's commands, even though they don't have the Law. This proves that the conscience is like a law written in the human heart. And it will show whether we are forgiven or condemned, when God has Jesus Christ judge everyone's secret thoughts, just as my message says."
Those are all neat verses, but I don't believe that the Bible is real. What is the evidence that the Bible is real, without using the Bible itself???
Change. Joy. Peace. These are just a few examples. The Bible is a book that changes people. It gives them joy and peace. It turns people's lives completely around. It has people do well. The Bible has been around for years and years, and yet Bible critics can not prove any part of the Bible to be in fault. Not one! They may have theories, but in time they realize that they have made a mistake or miscalculation or misconception. People die for this book. If the Bible is just a book with no spiritual impression then why are people willing to die for it? Why has the Bible not been proven wrong in all these years? Why does it change lives? Besides the prophecies for the future, why have all of the prophecies in the Bible been fulfilled even though the odds are against the possibility of that even to come about? Why does the Bible bring strength to the weak, comfort to the weary, hope to the hopeless, faith to the doubting, humbleness to the prideful, success to the failure???
I cannot deny the power behind the Word of God. It has been evident in my life. It has given me the greatest blessing I could desire. I see the results it promises when I follow it. It is more than just an ordinary book. Yes, it is far more than just ink on paper binded together inside a cardboard cover. It is a book that is complete truth. It has the message to change lives, as it did mine. There is no way that an ordinary book can do all this to so many people. There is no other book that brings the results as does the Bible. It is no wonder why the Bible is, by far, the best seller in the world!
