In John 1:1 we read, "In the beginning was the Word, and the Word was with God, and the Word was God."
From God's utterances came into being the Word, and from God's breath came into being the Holy Spirit. Thus, God the Father, the Word and the Holy Spirit together forming the Holy Trinity existed before everything was created.
By the Word, God's will is made known, and by the divine power of the Holy Spirit, God's will is put into effect, manifesting the works of the Holy Trinity through the action of a single entity.
An example of God's will at work occurred in Mark 1:16-17. When Jesus, acting as the Word, commanded Simon and his brother Andrew to follow him. They left their nets and followed him without asking where he was taking them.
Here, God's will was made known by Jesus: the personification of the Word. God's will was put into effect by the divine power of the Holy Spirit who moved Simon and Andrew to put their nets away and follow Jesus.
In Matthew chapters 5,6 and 7, Jesus gives several sermons among which are the Beatitudes. A careful reading of these chapters shows undeniably that they are the words of God made known to humankind through Jesus in his capacity as the Word.
When we recall that Jesus had no formal education during his upbringing, the view that the words of the Beatitudes came directly from God becomes more believable.
Even taking into account that Jesus' parents had taught him to read and write the Shema (Deuteronomy 6:4-9), and the Hallel or Psalms 113-118, it is inconceivable this rudimentary tutorial could have prepared Jesus sufficiently to produce the depth and breadth of the wisdom found in the first four books of the gospel.
To say efforts have been made over the centuries to discredit the view that Jesus spoke the words of the gospel would be an understatement. Literary giants like Lew Wallace and C. S. Lewis, only to mention two, tried to do so, but when confronted with the results of their own research, they accepted the divinity of Jesus in their books: "Ben Hur" for the former and "Mere Christianity" for the later.
