In the beginning John begins by quoting the opening words of Genesis in Greek (Gen 1:1). He uses Genesis 1:1–5 to establish the “Word” as a preexistent agent of creation present with Yahweh from the beginning.

This first section of the prologue (John 1:1–5) functions as an interpretation of Gen 1:1–5 read through the framework of Prov 8:22–31 (see note on Prov 8:22). This exegetical technique resembles a method of Jewish exegesis called midrash.

A midrashic interpretation typically begins with a text from the Pentateuch and explains it through allusions to a text from the Prophets or the Writings. John begins with a quotation that invokes the context of Gen 1:1–5 with its imagery of creation by divine word and opposition between light…

a [beginning] Greek: arche (GSN-<G746>), beginning, origin, first. The dateless past (Gen. 1:1; Pr. 8:23).

b [Word] Greek: logos (GSN-<G3056>) (see note, Acts 1:1). The Word refers to Christ (Jn. 1:14; Rev. 19:13) and proves His pre-existence (Mic. 5:1-2; Rev. 1:8,11; 2:8; 22:13-16). He is an eternal Being as are also the Father and the Holy Spirit (Ps. 90:1-2; Heb. 9:14). They make the Divine Trinity (1Jn. 5:7).

c [was God] Not only was the Word with God, but He was God and always will be as much divine as the other two members of the Trinity (Ps. 45:6-7; Isa. 9:6-7; Jn. 1:1; Heb. 1:8-12; Rev. 1:8,11; 22:13-16).

Jesus is the Word of God (this verse, John 1:14; 1 John 1:1, 5:7; and Revelation 19:13).
Jesus is not a created being. He is God who created all other beings (see my notes at Ephesians 3:9, Colossians 1:16-17, Hebrews 1:3, and Revelation 4:11). Jesus existed “in the beginning” with God (Genesis 1:1).

Note 1
The Greek word used here for “God” is THEOS, and it denotes deity as an object of worship. This word is used 1,338 times in the New Covenant. Only 13 times is the word used to express anything but eternal deity. Here, the word reveals Jesus as God in the flesh (John 1:14 and 1 Timothy 3:16. The Scriptures attest to Jesus’ divinity (Isaiah 9:6-7, Matthew 1:23, and 1 John 5:20).

God the Father called Jesus God (Hebrews 1:8). Jesus forgave sins (Mark 2:5 and Luke 7:48), a power that God alone has (Mark 2:6-7). Jesus received worship (Matthew 2:11; 14:33; 28:9, and 17), and that is reserved for God alone (Matthew 4:10 and Revelation 22:9). The term “Christ,” which is used 569 times in the New Testament, further establishes the divinity of Jesus (see note 2 at Matthew 16:16).

Note 2
Jesus is the Word of God. The Greek word that is used here is LOGOS, and it denotes “the expression of thought—not the mere name of an object” (Vine’s Expository Dictionary). Jesus totally expressed the thoughts of the Father and was manifest in a physical form so all the world could read them. Hebrews 1:3 says Jesus was “the brightness of his glory, and the express image of his person.”

It is also appropriate for Jesus to be called the Word of God because the physical body of Jesus was produced by God’s spoken word, not the usual means of a physical relationship between man and woman (see note 4 at Luke 1:38).
