Every religion has its own holy book. Each group try to prove their holy book to hold all the truth. Most of the time, they try impress people with scientific miracle in their book. This is not exclusive to Muslims only, even Hindus and Atheists do the same. The Hindu language, sanskrit, actually has the term "Vimana" that means flying vehicle. Does that mean Hinduism is the true religion? However, there's one big problem with Hinduism. Hinduism believe that the universe is eternal, while science has proven that the universe is not eternal. The universe expanded from one single point. How about Atheism who claim to be scientific, when faced with the question of the origin of universe, remain silent. They are forced to believe that in the beginning there was 'nothing' (or something-who-knows-what-but-it's-not-god) and then miraculously there was everything in order out of mere coincidence. Of course, anyone with the right mind would know that this is irrational.

But what about Islam? Does the Quran hold any scientific miracle?

Sura 88:20

And the earth how it is spread out?

It's quite easy to understand that according to the Quran, the earth is flat. You can even check the tafsir for this verse here and it only affirms the flat earth conception. The effort to defend this notion makes nothing but a fool of oneself. Especially, if one reads the following verse from the Bible:

Isaiah 40:22

He sits enthroned above the circle of the earth,...

This verse clearly states that the earth is round, no need for tafsir. The book of Isaiah was written around 800 years BC which means 1400 years before Muhammad. So, even if the verse 88:20 is somehow magically twisted and the word spread out (Da'ha) miraculously shifts its meaning from flat to spherical, it still does not prove that the Quran holds all the truth because the bible has already come up with this scientific fact hundreds of years before the Quran and Muhammad could have just easily plagiarized that, which he obviously did not. But the Bible doesn't stop there. It also contains prophecies that have been and yet to be fulfilled. One of the fulfilled prophecies that occurred during our generation is the following:

Jeremiah 29:14

"I will gather you from ALL the nations, and from all the places where I have driven you, says the Lord, and I will bring you to the place from which I cause you to be carried away captive."

Israel's existence today, and the re-gathering of the Jews from ALL parts of the world is an irrefutable proof that the Bible is truly inspired by God.

John 5:39-40

You search the Scriptures because you think that in them you have eternal life; it is these that testify about Me; and you are unwilling to come to Me so that you may have life.

Nevertheless, the purpose of the 'holy books' is not for us to learn science, which is why God has given us intelligence for that, or to simply know things to come through prophecies. They are things that affirm the validity of the book but the main purpose of these 'holy books' is supposedly for us to get to know God more and attain salvation. But can a book contain everything we need to know about God? Can we learn all the truth just from books?

Now, this is where Christianity stands out from any other faith:

John 16:13

But when He, the Spirit of truth, comes, He will guide you into all the truth. He will not speak on His own; He will speak only what He hears, and He will tell you what is yet to come.

Jesus promises that He will send the Spirit of Truth to all His disciples. Obviously, Muhammad can not be the Spirit of Truth because Muhammad was very deceptive and he was only born 500 years after the death of the early disciples of Jesus. So, if Muhammad was the Spirit of Truth, then Jesus had lied because His early disciples didn't receive Muhammad.

The Holy Spirit is what makes Christianity unique. God didn't promise to send a book. No, what God promised was His very own Spirit. The apostleship ended with Muhammad in Islam. But in Christianity, Jesus was the beginning of apostleship and His disciples keep growing in number even up to now. All this is the work of the Holy Spirit.

2 Corinthians 3:6

He has made us competent as ministers of a new covenant—not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.

A Christian is led personally by the Holy Spirit that gives (spiritual) life. This is what religious people don't have, spiritual life. Religious people are only led by letters, books, rituals. Their understanding of god is limited to what the letters say. They do not have the luxury of experiencing God in their life, to have His love in their heart. Christians really get to know God because He lives inside them, not just from a book. When spirit-filled Christians reads the Bible, they read the Bible in the light of Holy Spirit, not leaning to their own understanding.

The battle of holy books may continue but Christians they believe in the living God. Even if all the Bibles are burnt, God's Spirit is still at work. You can not limit God and contain Him to only a book(s). This is why God sends His Spirit to guide us to all the truth. In some occasions, God has spoken to me verses from the bible and I never try to memorize them. He can speak His Word directly to our heart. So, even though reading the correct book matters, but what truly makes a difference is the spirit guiding you, is it the Spirit of Truth or the spirit of error/deception?

Matthew 7:16

By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles?
