'In the beginning was the Word and the Word was with God and the Word was God' - what does that mean?

It means that in the beginning, as from Adam and Eve, the Gospel of Jesus Christ was preached; And the Gospel was the Word, meaning that the Word Jesus preached was of the Father, as Jesus did the will of the Father; And Jesus was sent by the Father, and He spoke for and in the name of the Father and He was one in mind, body and thought with God the Father. To put it simply: The Word, or the Truth was with Jesus Christ, and the authority and power of God to deliver the Truth was with Him also.
