The Gospel of John is the most theologically refined of the four gospels. There are the Synoptic Gospels, Matthew, Mark and Luke, and then there is the Fourth Gospel, "shallow enough for a child to wade in, but deep enough for an elephant to swim in."
The Gospel of Matthew holds a special concern for its Jewish readership and audience. It deals specifically to the royal lineage of Jesus as the Son of David, and the fulfillment of the Hebrew scripture and its messianic expectation, and finally Jesus' identity as the Son of God who rises from the dead after taking upon himself the cross, to deal with sin of human kind on behalf of the Father, as well as to seek His forgiveness as the ultimate mediator for all eternity.
