You want proof its true? I'm no theologian but I can give you a few things I did learn at scripture class. (No, I don't do Studies of Religion)
Scholars, historians, archaeologists regard the Bible as a historical document i.e. It's NON-FICTION. It was written by man, yes, and there so many things in it that doesn't even seem ... plausible, or believable, true, but it was written by learned people who lived during that point of time (they were able to write it down, which makes them, if not experts, then reliable to an extent since how many people during 1400BC even knew how to write?) --- except for the Pentateuch, which Moses wrote (he was a Hebrew, but lived as an Egyptian Prince, and they've already developed a writing system 2000 years before), and he was only present during Exodus to Deuteronomy, not Genesis, nobody lives that long --- and it wasn't written like: 'I've heard about this from ... who heard it from .... who heard it from his uncle ... who then heard it from his sister ...'. The authors really did live through the experiences first hand and the circumstances they wrote about did occur in history.
The basis of the Christian faith, among other things, is Jesus Christ fulfilling all the prophesies during his birth and throughout his life. All throughout the Old Testament, there were many prophesies concerning the 'Messiah', for example, how exactly Christ was going to be born (picked this one out because its that convinced me ... seriously, I thought JC was a product of a time machine experiment one point of time ... you cannot disprove time travel btw).
Jesus Christ may be able to 'fix' his miracles to make it seem astounding to a few thousand peasants e.g. bringing the dead back to life, turning dirty water into wine, healing the uncurable ... but the one thing he cannot 'fix' are the conditions in which he was born. What would happen at the time of his birth was written in the Old Testament, 400+ years before.
1) Jesus would be male: Genesis 3:15; Isaiah 9:6 ... Did you have any say what gender you wanted to be when you popped out? Even our DNA research isn't as advanced as that.
2) JC was Shem's, Abraham's, Isaac's, Jacob's, Judah's, Jesse's, King David's, and King Solomon's descendant: as prophesied in Genesis, 2 Samuel 7:12-16, fulfilled in Matthew 1:3-6. Jesus Christ is the 10th Generation descendant of an Israelite king. On the other hand, King Solomon had a harem of wives and by the 10th generation, he would have had a whole number of male descendants to name as the Messiah....
3) The Messiah would be preceded by a prophet:The only (and last) prophet in the New Testament is John the Baptist (who got beheaded), and the last prophet named by God before him was Malachi, 300-400 years before. John the Baptist was the cousin of Christ, and came before Christ....
4) Jesus born from a virgin: prophesied Isaiah 7:13-14, fulfilled Matthew 1:18-25; Luke 1:26-35. Mary was 14. Joseph was her first marriage. JC was conceived and Joseph didn't touch her... Artificial insemination wasn't available in 4-6BC. So something must have happened.
5) Jesus born in Bethlehem: prophesied Micah 5:2-3, fulfilled Luke 2:1-7; Matthew 2:1-6. Mary and Joseph both lived in Nazareth, and around 5BC, and coincidentally the Roman emperor ordered a census to count how many people there are in the Roman empire so that he could evaluate his riches, I suppose. They had to travel to Bethlehem while Mary was enciente so that they could be counted.
6) The Star of David would be present during his birth: prophesied Num. 24:17; fulfilled Matt. 2:1-9
... There are way too many coincidences to disprove that he was the promised Messiah. **There are heaps more prophesies about his life, as well, but I won't bore you. We believe that, if he was what the Old Testament promised he would be and more, then he is God.
Also, you cannot disprove Jesus' existence or the foundation of his fame as a miracle worker. Rome's most famous historian, Cornelius Tacitus, even said: 'Christians derived their name from a man called Christ, who, during the reign of Emperor Tiberius had been executed by sentence of the procuator Pontius Pilate' Annals 44:2-3. This was rather a neutral description, but there were other writers, Thallos, Mara bar Serapion, Flavius Josephus who have mentioned Jesus in the texts that were found. (No, I'm not throwing names around, they are legit first century writers.)
Also, it is a myth that we have to basically live inside a box of rules to make it up to God ... that's absolute crap. We're already catching a free ride to 'heaven' because we choose to believe in Christ...
Have you ever even read the Bible? If so, please tell me what inconsistencies there are because it's so straightforward to me.
