Don't the four Gospels contradict each other?

Their differences are the kind found in genuine independent witnesses, differences of emphasis, order, and detail, not of the central events. On the cross and the empty tomb they speak with one voice, and their variety is a sign of honest testimony rather than a scripted story.

Which Gospel should I read first?

Many people start with Mark, the shortest and most fast-moving, or with John, which reflects most directly on who Jesus is. Any of the four is a good place to meet him; the others then fill in the portrait.

Why are there four Gospels?

Q: Why are there four Gospels?

Because four early witnesses told the one story of Jesus for different audiences and from different angles. Their agreement on essentials with variety in detail is a mark of independent testimony, not collusion. Four complementary portraits give a fuller picture of the same Jesus (John 21:25).

The short answer

There are four Gospels because four early witnesses told the one story of Jesus for different audiences and from different angles, the way four honest witnesses to the same event each add what they saw. Their agreement on the essentials, with variety in the details, is a sign of independent testimony rather than a scripted account. Far from weakening the story, four complementary portraits give us a fuller picture of the same Jesus.

It can seem odd to have four accounts instead of one. But think of how a real event is reported. Four truthful witnesses will agree on what matters and differ in emphasis and detail, because each stood in a different place and remembered different things. A single, perfectly uniform account would look more like collusion than testimony.

Four angles on one Jesus

Matthew writes to show Jesus as the promised Messiah of Israel; Mark gives a fast, vivid account of Jesus the servant who acts; Luke, a careful historian, highlights Jesus for the outsider and the overlooked; John reflects more deeply on who Jesus is as the eternal Word. Different readers, different purposes, one Lord.

“And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books.”
John 21:25

The variations between them are the kind you find in genuine independent reports, not the kind that undo the story. Where they overlap they confirm each other; where they differ they enrich. And on the center, the cross and the empty tomb, they speak with one voice.

It comes back to Jesus

Four Gospels mean four witnesses inviting you to see Jesus from four sides and arrive at the same person. That is their whole aim. If you want to know why Christians stake everything on him, the simplest step is to read one of these accounts and let the others fill in the portrait.
