John 16:9

9 Of sin, because they believe not on me;

Ver. 9. Of sin, because they believe not in me ] Our Saviour points out the greatest of sins, unbelief; which was the first sin, and is still the root of all the rest, Hebrews 3:12 . It is a sin against the gospel, and rejects the remedy, that bath of Christ’s blood, to the which even the princes of Sodom are invited, Isaiah 1:10 . It gives God the lie, and subjects a man to the rigour, coaction, and curse of the law.
