John 1:1 can just as easily be translated "and the Word was a god", depends on one's theological leanings. And no, I'm not Jehovah Witness.
John is consistent in all of his writings throughout the New Testament. The prologue can only be understood when compared with all of his writings, which teach that Jesus is the Son of God, a person sent from and by God to do and speak His will, in accordance with the prophesy of Moses, Duet. 18:18. When scripture is rightly divided (harmonized together) the truth is evident.
"In the beginning God SAID, 'Let there be light'", etc. Gen. 1
"In the beginning was the word (logos), and the word (logos) was with God, and the word (logos) was God." John 1:1
The world was created by the breath of His mouth, Ps. 33:6. He spoke and it was. Ps. 33:9
God created by speaking al things into existence (God's logos/word). So, the word/logos of John 1:1 is not a person. It's the spoken word of God. The word "word/logos" is used throughout John's writings and never means a person in one instance.
The harmony of scripture tells us that the Greek word, “logos”, is the tangible spoken word that reflects the rational; a person’s mind, reason, thoughts, plan, intellect, and motives. When we speak, our voice goes out from us and our silent thoughts become audible. They reflect our intangible thoughts and reasoning powers. The root of “logos” is “to speak”. Speaking is an outward projection of our thoughts. The word of a person has no personality beyond the personality of the person whose word it is.
The word/logos of God became flesh in that the flesh and blood person, Jesus Christ, did and spoke what the Father commanded him, thus representing God expressly, just as Duet. 18:18 indicated he would.
I Timothy 6:14-16 all by itself is the glaring fact that ONLY God the Father has inherent immortality:
Jesus Christ will show (>), “… Who is the blessed and
only Potentate, the KING of kings, and LORD of Lords;
Who ONLY has immortality,
dwelling in the light which no man can approach unto; whom no man hath seen, nor can see; to Whom be honor and power everlasting. Amen.” I Tim. 6:14-16
Jesus' purpose was to represent the Father expressly and to be the vehicle of redemption for mankind. Jesus could bleed and die. Jesus could take on the sins of the world. God is spirit and He is light. He cannot interface with sin and darkness, but his messengers can speak for Him and represent Him, a thing that Jesus Christ, servant of God, did. (Acts 3:26, Heb 1:1)
