Although Christians possess what they call the four Gospels (Matthew, Mark, Luke, and John), these are not four different and contradictory narratives, but rather a relating of the same story from four different angles.
Let me illustrate this statement. Imagine a family around the corner in a traffic accident. The father may be a witness to the brand and model of the two cars involved. The mother can specify the colour of the cars and the number of their occupants. Their young son will point out that a puppy has almost been crushed, while his little sister will only talk about a doll fallen from a door. So who is telling the truth? All tell the truth, but have seen the same event from different points of view.
In the same way, the four evangelists tell the same story of the life of Christ, but not all of them focus on the same thing. They relate the same facts according to their purpose and emphasis for their readers. Matthew seems to address himself especially to the Jews focusing on Jesus as a true king of the kingdom of heaven. John and Luke write more for the non-Jewish reader. Luke also writes things in their chronological order. Mark is concerned far more with the actions of Jesus and John majors on his words.
The four evangelists, however, all agree on the essential elements of the life and teaching of Jesus Christ, and they do not contradict each other. The comparison of their four accounts gives us the richest and most complete picture of the life and work of Jesus the Messiah.
At the time of Christ, the Near East, where Christ was born and raised, was under the influence of the Roman Empire and its Greek based civilization. The Greek legal system required at least two witnesses to go to court. Moreover, the Bible confirms: “… Every case will be settled on the declaration of two or three witnesses. (2 Corinthians 13: 1)
In his sovereignty, God gave four witnesses whose testimonies agree on the life of Christ. The Gospels are like facets of one glorious and precious diamond.
