He did not open their understanding without the Scriptures, he sends them thither; and he knew the Scriptures would not sufficiently give them a knowledge of him, and the things of God, without the influence and illumination of his Spirit: they are truly taught of God, who are taught by his Spirit to understand the Scriptures. Christ gives a great honour to the Scriptures. The devil cheats those souls whom he persuades to cast away the Scriptures in expectation of a teaching by the Spirit. The Spirit teacheth by, not without, not contrary to, the Holy Scriptures.
