Being originally written (as is thought) for Romans, there are very few references to the Old Testament Scriptures contained in this Gospel. Jewish words are explained (Chapter 3 v 17; 5 v 41; 7 v 11, 34; 14 v 36); and also Jewish customs (Chapter 7 v 3 to 4; 14 v 12; 15 v 42). Latin expressions are frequently used such as Legion, Centurion, etc. The Romans admired action, and this Gospel depicts the Lord as a worker.

The book of Luke gives us the most complete look at the life of Jesus. Luke uses eyewitnesses as sources for his writings. He stresses Jesus' humanity (since Luke was a doctor himself) and compassion as well as the power of the Holy Spirit and of prayer.

The book of John was written in order that men may believe that Jesus is the Son of God and consequently the Redeemer of all who believe in him and the things concerning the Kingdom of God. John cites eight signs to establish and prove this point, culminating in the resurrection of the Lord Jesus. John is the only one of the four Gospels that does not cite any parables; instead John emphasizes Jesus as the manifestation of God.

There are many key words in John's Gospel, and dominant throughout is the word "believe", which occurs over eighty times. The word, however, implies a belief that has developed into faith or conviction. As such, this Gospel was written for believers. They are enabled thereby to perceive the inner strength of Jesus, and to see that it stemmed from a greater than he, even God. Another peculiarity is the frequent use of the word "Jew". It is only found once in Matthew, twice in Mark and in Luke, but over sixty times in John.

John concerns himself more with the Judean ministry, which Matthew and Mark hardly touch upon, and he records eight miracles (which he terms "signs") that set in sequential order the whole purpose of God in Christ.
