Divine Deliberation and the Creation of Man

Genesis 1:26

“Then God said, ‘Let us make man in our image, after our likeness.'”

Luther’s Commentary
“Moses is here celebrating the formation of man as having been wrought by a peculiar design and contrivance of the mind of God; my own opinion is that all the other animals of the earth stood forth created in a moment, as the fishes were made on a sudden in the sea…let us now approach the last and most glorious work of God: the creation of man! God says, ‘Let us make man in our image, after our likeness.’ Here again Moses adopts a new phraseology. The divine expression is not in this place, ‘Let the sea be moved,’ or ‘Let the earth bring forth grass’ or ‘fruits.’ But the remarkable Word of God here is, ‘Let us make, or form, or fashion, or fabricate man.’ Wherefore this expression implies manifest deliberation and counsel; the like of which is found not in the creation of any former creatures. In those cases God says simply without any deliberation, counsel or particular design of mind, ‘Let the sea be moved;’ ‘Let the earth bring forth,’ etc. But here where God wills to create man, he turns himself as it were to deep thought and enters into profound counsel and deliberation…All three Persons here concur and speak unitedly when they say, “Let us make.” For neither does the Father make any other man than the Son makes; nor does the Son make any other man than the Holy Ghost makes. But the Father, the Son and the Holy Ghost, the one same God, are the one same author of the one same work and are the one same creator.”
