Some people question the bible.  Some flat out don't believe in it, but there is proof that the bible is real.  God gave us prophecies so we can validate the bible. The bible is flawless.  It has hundreds of prophecies in it and they were all fulfilled. All we are waiting on is the seven year tribulation and the second coming of Christ.  Jeremiah prophesied that Israel will be scattered.  He even said who was going to take them over. 

In 70 A.D that was fulfilled.  Then Ezekiel prophesied Israel would become a nation again in Ezekiel 37, which was fulfilled May of 1948.  

In 1940 the Dead Sea Scrolls were found which was the Old Testament Bible in it's original Hebrew language.  Some prophecies about Jesus are in it that were written 1000 years before he was even born. 

Flavius Josephus and Tacitus were historians employed by Rome who made recordings about the death of Jesus Christ. Josephus even wrote about his resurrection. 

Also another historical reference outside the bible is the Talmud.  It's a Jewish commentary that  contains references to Jesus and confirms the book of Mathew.

It is a historical fact that Jesus existed and was crucified.  The only question is whether he rose from the dead.  After Jesus was crucified all of his disciples were scared for their lives so they went into hiding. They thought Jesus had deceived them.  How could he be the son of God if he was dead?  Then all of a sudden they all came out of hiding to spread the Gospel.  They were all killed for spreading the Gospel.  What changed their minds?  They saw the resurrected Christ.  It is a historical fact that 500 over people saw Jesus after he rose from the dead.  If you had 500 witness for a murder case that would be more than enough evidence to convict someone in a court of law. 1 Corinthians 15:6 also refers to the 500.

There is a lot of prophecies about Jesus.  Isaiah prophecies in 700 B.C.  in Isaiah 7:14 that a virgin will have a son and name him Immanuel.  Which was fulfilled in Mathew 1:18-23. 

In Micah 5:2 Micah prophecies that the Messiah who come from Bethlehem.  Which was fulfilled in Luke 2:4. 

In Zechariah 9:9 Zechariah prophecies in 520 B.C. that the Messiah will have salvation and be humble enough to ride a donkey.  Which was fulfilled in Mathew 21:2. 

In Isaiah 50:6 it talks about how the Messiah will give his back to those you strike him, Referring to his back being whipped. 

It also talks about him being spit on and humiliated.  Which was fulfilled in Mark 14:65.  In Isaiah 53:2-12 In verse 2 It talks about the Messiah having no Majesty.  Jesus was a Galilean.  The Galileans were poor and often looked down upon.  In verse 3 it talks about him being despised and forsaken by men.  In verse 5 it talks about him being pierced for our transgressions, Referring to his hands and feet being pierced with nails and his side being pierced with a spear.  And this was done for our sins. 

In verse 6 it talks about how the Messiah will cause all of our iniquities to fall on him, Referring to him dieing for our sins.  In verse 7 it talks about how he didnât talk when he was like a lamb being led to the slaughter, Referring to him not defending himself when he was being sentenced to death. Which was fulfilled in Mathew 27:14. In verse 12 it talks about him pouring himself out o death, Referring to him dieing for us. 

In Psalm 22:14-18  David prophesied in 1000 B.C. in verse 14 that the Messiah will be poured out like water, referring to the water that poured out for his side when he was speared in the side.  Which was fulfilled in John 19:34.

In verse 15 it talks about how his tongue cleaves to his jaws, referring to dehydration. Which was fulfilled in John 19:28. In verse  16 it talks about his hands and feet being pierced, referring to his hands and feet being nailed to the cross. 

In verse 18 in talks about people casting lots for his garments, referring to the Roman soldiers gambling for his clothes.  Which was fulfilled in Mathew 27:35.  

In Psalm 16:10 it talks about the Messiah will not undergo decay, referring to him being resurrected before his body could start to rot. 

In Isaiah 53:12 it talks about the Messiah pouring himself out to death and barring the sins of many, referring to him dieing on the cross for our sins.  Is all of that just luck or quensidence?  That is just a sample of bible prophecy.  There is much much more.
