The Spirit of Christ to Laodicea
14 “To the angel of the assembly in Laodicea write: “The Amen, the Faithful and True Witness, the Head of God’s creation, says these things:

Rev 3:14
the beginning of the creation of God – see also Revelation 4:11. This takes us back to John 1:1, the Spirit of Christ was the “firstborn,” and the “only begotten God” (Col 1:15; John 1:18; Heb 1:6). He was the firstborn Spirit. To interpret this as saying the Spirit of Christ was “the originator of the creation of God” is unfaithful to the Greek language, which gives us only one meaning of “beginning” in every verse of the New Testament, including John 1:1. We can consider the meaning of “beginning” in Mark 13:19, “For those days will be a time of tribulation such as has not occurred since the beginning of the creation which God created until now, and never will.” This is the most direct comparison to Rev 3:14, and gives the same meaning as “beginning.”
Even the Trinitarian Albert Barnes in his commentary on this verse, and the use of the word “beginning” in the New Testament, says: “The word (ἀρχὴ archē, beginning) is not, therefore, found in the sense of authorship, as denoting that one is the beginning of anything in the sense that he caused it to have an existence.”
The Father, who makes all of us in the womb, (Jer 1:5; Psalms 139:13; Isaiah 44:2), is the creator and Father of all (Eph 4:6).
20 Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him, and will dine with him, and he with me.
Rev 3:20
I stand at the door and knock – most people interpret this statement as simply referring to the “lukewarm” nature of this Church. But the meaning of this goes back to verse 8, “I have before you an open door – because..you have kept My word.” Christ promised He would make His home with us if we keep His word (John 14:23).
