John 1:10 - Ellicott's Commentary On The Whole Bible

In the world. — This manifestation in the flesh recalls the pre-incarnate existence during the whole history of the world, and the creative act itself. (Comp. John 1:2-3, Note). The two facts are the constant presence of the true Light, and the creation of the world by Him. The world, then, in its highest creature man, with spiritual power for seeing the true Light, ought to have recognised Him. Spirit ought to have felt and known His presence. In this would have been the exercise of its true power and its highest good. But the world was sense-bound, and lost its spiritual perception, and “knew Him not.” This verse brings back again the thought of John 1:3-5, to prepare for the deeper gloom which follows.
