"Jesus Interrupted" by Bart Ehrman is a very great read on this very subject.
This book is about how certain kinds of faith (particularly the faith in the Bible as the historical inerrant and inspired word of God) cannot be sustained in light of what historians know about the Bible. Ehrman begins by describing the difference between a vertical reading of the Gospels (Matthew, Mark, Luke and John) with a horizontal reading of them. A vertical reading is simply taking one Gospel at a time and reading through it. A horizontal reading, however, is where we place the gospels side by side and read them together to see the differences in the accounts. When we read the Gospels horizontally we find discrepancies, irresolvable differences, and even contradictions, not only in the small details, but also when it comes to major ideas presented by the authors.
One that stands out to me most is the death of Judas Iscariot. In the gospel account of Matthew, it has Judas hanging himself, while in the book of Acts it states he fell over and his guts bursted open. So which is correct?
There are significant differences between Matthew and Luke concerning various aspects of the birth of Jesus, as well as the genealogies found in their stories.
Other discrepancies concern things like what the voice from heaven said at Jesus's baptism
What Jesus did the day after his baptism
Whether or not Jarius's daughter was already dead when her father approached Jesus
Who is for and against Jesus
Was Jesus crucified before or after Passover dinner
What happened immediately after his birth
There are many many others but that is for you to investigate. I hope this helps you Recovery, this isn't something that I have presented to deter you from your faith. You can still be a believer and know the discrepancies found in the text.
