“The knowledge of Jesus Christ is the very marrow and kernel of all the Scriptures; the scope and center of all divine revelations: both Testaments meet in Christ.
The ceremonial law is full of Christ, and all the gospel is full of Christ: the blessed lines of both Testaments meet in Him.
And how they both harmonize, and sweetly concentrate on Jesus Christ, is the chief scope of that excellent epistle to the Hebrews. For we may call that epistle the sweet harmony of both Testaments.
The right knowledge of Jesus Christ, like a clue, leads you through the whole labyrinth of the Scriptures.”
–John Flavel, The Works of the John Flavel (Carlisle, PA: Banner of Truth, 1820/1997), 1: 34.
