Absolutely, the Logos/Word is clearly identified as the creator. Not only here at John 1:3 but at Colossians 2:16 as well as by His own Father at Hebrews 1:10.
Colossians 1:16, "For by Him all things were CREATED, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities--ALL things have been created by Him and for Him.'
Now, there is a difference between the word "by" (which is a preposition) and the word "through. "By" is used to indicate origin or the manner of something. "Through" is used has a function word to indicate means, agency or because of.
You quoted Romans 5:11 and said this: "We note we are rejoicing IN GOD not in Jesus." The Apostle Paul stated at Philippians 3:1, "Finally, my brethren, rejoice in the Lord." At vs3, "for we are the true circumcision, who worship in the Spirit of God and GLORY in Jesus Christ."
Philippians 4:4, "Rejoice in the Lord always; again I will say, rejoice!" You can't have one without the other. This is why I keep bringing up Isaiah 44:24, "Thus says the Lord, your Redeemer, and the one who formed you from the womb, I, the Lord, am the maker of all things, Stretching out the heavens BY MYSELF, And spreading out the earth ALL ALONE."
Since this is true, how do you reconcile these statements with John 1:3, Colossians 2:16 and Hebrews 1:10? Since the Lord created all alone and by Himself why does the Bible include Jesus Christ as the creator?
Here's another example that needs to be reconciled. Isaiah 43:11, "I, even I, am the Lord; And there is NO savior besides Me." Now going back to Philippians 3:20, "For our citizenship is in heaven, from which also we eagerly wait for a Savior, the Lord Jesus Christ."
How many times have people said, "Jesus was made Lord," quoting Acts 2:36, "Therefore let all the house of Israel know for certain that God has made Him both Lord and Christ--this Jesus whom you crucified." Luke 2:11, "for today in the city of David there has been born for you a Savior, who is Christ the Lord." He was already a Savior and Christ/Messiah the Lord to begin with.
