Adam Clarke
I am come a light into the world - Probably referring to what his forerunner had said, John 1:5. Before the coming of this Savior, this sun of righteousness, into the world, all was darkness: at his rising the darkness is dispersed; but it only profits those whose eyes are open to receive the rays of this sun of righteousness. See on John 1:5 (note); John 3:19 (note); John 8:12 (note); John 9:5 (note).
