Then you aren't talking about asyndeton. Because what you have written here has no parallel in the Greek text.Lol! I'll repeat it word for word:
All things were made through the personal agency of the Word, and so apart from him nothing was made through the personal agency of anyone else.
But the life that was the light of men was made in him and the darkness has not overtaken it.
The asyndeton provides a contrast between the two statements.
Or whatever other drivel you would write in place of actual substance. Your argument just took two to the head, and you're too busy proving you have no idea what you are talking about.
