Genesis 11:7-8
7 Go to, let us go down, and there confound their language, that they may not understand one another's speech. 8 So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to build the city.
What this passage establishes
The LORD’s ‘let us’ language is again followed by the LORD acting as the single divine agent.
Why it matters in the argument
Scripture says God created alone, then the New Testament places creation in Christ. The identity claim is stronger than merely saying Jesus assisted another Creator.
Apostolic connection
Because the LORD says He created by Himself, New Testament creation passages reveal Jesus within the identity of the one Creator.
Common misunderstanding
Language such as ‘by’ or ‘through’ does not require a second creator beside God; Scripture also describes God creating by His word, wisdom, power, and will.
How to use it in conversation
Pair an Old Testament ‘created alone’ passage with a New Testament passage that attributes creation to Christ.
