The Testimony in the Word
The testimony of the Spirit of God in the word itself—witnessing it to be of God, by that stamp and impress, or, which comes to the same, by those notes and marks of divinity which everywhere appear in it—is the immediate and principal, and a sufficient, reason of our believing it to be the word of God, and the medium the Spirit useth in working faith in us, or making us assent to the divinity of the Scripture.
