All things were made through Him, and without Him nothing was made that was made. (Jn. 1:3)
He is the image of the invisible God, the firstborn of all creation. (Col. 1:15 NASB)
The answer to the question posed in the title of this teaching is “yes” – Jesus is eternal and He is the firstborn of all creation. While there isn’t a contradiction that exists between both of those suppositions, there can appear to be one if the use of the word firstborn in Colossians 1:15 is misunderstood.
