Why should I believe the Bible, everybody knows it’s full of contradictions.

Actually, the Bible is not full of contradictions. It does have parts that are difficult to understand that people interpret as contradictions, but with some basic knowledge of the text those misunderstandings fade away. Here is an example:

Why do the inscriptions on Jesus’ Cross differ among the four gospel?

And they put up over His head the accusation written against Him: THIS IS JESUS THE KING OF THE JEWS. Matthew 27:37

And the inscription of His accusation was written above: THE KING OF THE JEWS. Mark 15:26

And an inscription also was written over Him in letters of Greek, Latin and Hebrew: THIS IS THE KING OF THE JEWS. Luke 23:38

Now Pilate wrote a title and put it on the cross. And the writing was: JESUS OF NAZARETH, THE KING OF THE JEWS. John 19:19

The charge against Jesus was written in three different languages: Greek, Latin and Hebrew. Since Matthew’s audience was mainly Jewish, he likely quoted the Hebrew inscription. Luke’s audience was the Gentiles and he likely quoted the Greek inscription. John writes that Pilate wrote the inscription and since Latin was the official language of the Romans, John likely quoted the Latin inscription. Mark, perhaps shortened his version of what he witnessed. The content of all four inscriptions was the same and the differences can be attributed to the language of the inscription being quoted by the author, or the author’s liberty to quote the part of the sign that he thought was sufficient in his historical account of the events.

The Bible has many passages that are hard to understand because of differing styles of literature, translating words from ancient Hebrew or Greek, or a misunderstanding of context. But all of these passages can be cleared up with additional study.

Now to those who still believe the Bible is full of errors, you do so because of your beliefs. You want the Bible to have contradictions so when you read a text that is difficult, you interpret it as a contradiction or error even though it’s not. Be honest with yourself… You do not want a God that can tell you what to do and what not to do.
