First off, I'd like to say that the Bible is a true book, not a book of fairy tales.
Why would I believe this?

Well, firstly, because the Bible is true, and proves itself to be true.
The bible is 30% prophecy, with a fulfillment ratio of 100%. Prophecies so exact that even names are given hundreds of years before they were born, such as King Cyrus prophesied about in the book of Isaiah (44:28). (The Dead Sea scrolls gave us a copy of the Isaiah scroll that is dated around the time of Jesus.) We know that the book of Isaiah that we have had in our bible all these years is a match to the oldest known scroll copy, so we know it is unchanged in context and content. Similar to the plates that a $20.00 bill are created without flaw to make exact copies, so in the same way the scrolls were copied almost perfectly as a copy, of a copy, of a copy etc. We do not have the originals but there has never been any flaw found that affects the doctrine in any way. Only a couple of non important copy errors not affecting anything important. Another person named by name before he was born was Josiah (1 Kings 13:2). Not just names of people were in prophecy, but events. Most notably 353 prophecies that Jesus fulfilled regarding the coming Messiah (Odds of 1 man fulfilling this many prophecies is mathematically improbable. Basically impossible), and the formation of Israel coming together as a nation on May 15, 1948 as prophesied in the book of Ezekiel in the valley of dry bones.
Can a nation be formed in a day after not being a nation for 2000 years in their land?
This has NEVER happened in history before...with all language and national, cultural and ethnical factors intact. Surely this was done to show God is real and true to His Word.
Modern scholars believe that the 66 books of the Bible were written by at least 39-40 authors over a period of 1,500 years. Written by Sheepherders, Farmers (Amos), Kings (David, Solomon), and people from all walks of life. Poor to rich. All perfect in harmony without contradiction.
Other religions have books written by 1 person over a short period of time, with no archeological evidence to support anything whatsoever.

Secondly, the Bible makes claims that it is true and inspired Word of God. In several places it makes claims that the "Lord said".

It is a Jewish book, written by all Jewish authors (with the "possible exception" of Luke in the New Testament). All the apostles were Jewish, Jesus was (and is) Jewish,
all the early Church was comprised of Jewish Believers in Christ, worshiping in Jewish Synagogues with Jewish people, and in homes. When the Jewish people rejected Jesus as the Messiah (They did not reject Messiah, only that Jesus was Messiah - They believe to this day that a Messiah is coming) this paved the way for non Jewish believers to be grafted into the shared worship of Messiah.
The Message was for the Jew first, then the Gentile (Non-Jew), and Jesus commanded His followers to go out to Jerusalem, then Samaria, then the world. First to His Chosen people, then to anyone who has ears to hear. This is good news!!

The Bible shows that there are some prophecies still to happen. Such as the Temple in Jerusalem will be rebuilt when a peace treaty is confirmed for 7 years. The peace treaty will be broken after 3.5 years (temple sacrifices will be restored and then halted) and the Anti-Christ will be revealed proclaiming himself as god in the Temple. Then the great tribulation will be so bad that God Himself will intervene so that life doesn't get wiped out from the earth as would happen if He didn't step in. There is a description of Fire and eyes dissolving in their sockets (Sounds like Nuclear war). So we know what is to come before Jesus comes back as He said that He will.

God's scriptures show us that through one man (Adam) who sinned, and passed down the Sin genetics, and penalty, that all sin, and fall short of what is required to get into Heaven.
God's standard is perfection. We can never be "good enough" to get into Heaven.
The 10 commandments from Exodus 20 are familiar to most people.
Thou shalt not murder... Jesus said that if you hate someone then you've murdered them in your heart. God's standard is so perfect that He looks into your heart... This means that we are all guilty. Well there were actually more than 10 commands. The Jewish people believe that the Old Testament (The first part of the Christian Bible) contained 613 commands!
Jesus was showing us that we are all guilty of offending God's laws and commands and we owe a penalty for our transgressions of the law (Sins). The penalty for even 1 small sin, is death. Blood is required...not a drop, but the life that the blood sustains.
We are all guilty, even from birth. innocent babies still are sinners thanks to Adam's transgression.
We are not sinners because we sin. We sin because we are sinners. We are born with original Sin. So now what? We all deserve death? Yep. Sadly, we all deserve death immediately.
Thankfully, God Provided a payment for the price owed.
Because He is just, and must righteously punish sin, He sent His Son, Jesus to live the perfect life that we were not able to do for ourselves, and Jesus willingly went to the cross, and willingly laid down His life to pay what was owed.
If we believe that He died willingly for us to pay the penalty of our sin, that He rose again on the third day after being crucified, that He rose in the flesh (not just as a spirit) and we repent from our sin (Repent means to change our mind, turn away from), He will give us eternal life. Not just spiritual life, but to be adopted as Sons and daughters into God's family. To inherit all things. What does God own? All things.
We hear His voice through the hearing of and reading of His Word. He said my sheep hear my voice, and I give them eternal life.
Another thing Jesus said was that all of the commandments can be reduced down to two commands:
“You shall love the Lord your God with all your heart, and with all your soul, and with all your strength, and with all your mind. And love your neighbor as yourself.” (Everyone is your neighbor).

I didn't write this to bore you, but for you to know and understand that there is a God who LOVES you enough to lay down His life for you.
A Father better than your earthly Father. If you accept Him and let Him be your Father.
As through one man (Adam) all were condemned, through one man (Jesus), all men can be saved!

If you want to know more, just ask me!
If you want to accept Jesus into your life, Ask Him! By no means will He turn you away!
