John Gill Commentary John 8:32

"and ye shall know the truth, and the truth shall make you free." — John 8:32 (ASV)

And you shall know the truth
Either the truth of the Gospel, the truth as it is in Jesus; meaning, that they should have a larger knowledge of it, while others are ever learning, and never come to the knowledge of the truth; but the spirit of truth should lead them into all truth, and cause them to grow and increase in Gospel light and knowledge; or Jesus himself, who is the way, the truth, and the life; and the sense is, that they should know more of him, of the dignity of his person, of the nature and usefulness of his offices; of the efficacy of his blood, the excellency of his righteousness, and the fulness of his grace, and that for themselves:

and the truth shall make you free ;
from ignorance and error, and the prejudices of education, under which the whole nation laboured, and from the thraldom of the law.
