That true holiness consists especially in the inward impressions and dispositions, which make a man meet for communion with God, and in the inclinations, and carriages of the soul towards God immediately, such as mere Moralists never knew. There’s a fountain and a root within, from which springs all that honesty, and integrity, and purity which appears in the outward conversation, and all is from man’s being engrafted into Christ, and receiving from him a continual supply of his Spirit. And this (I hope) Papists will not deny, viz. That all spiritual good is wrought in us by the Spirit of God.
Now this way of holiness being taught us in the Scripture, we conclude Scripture to be written with God’s finger, because no other than God could reveal such glorious truths to us. Let it be showed us, how these things came to be written where we find them, if God did not. Once we think it a rational and unquestionable conclusion, That Scripture is given by inspiration of God, because we find in it the only way of our access to, and acceptance with God, and the only way of purifying us so, as we may meet for communion with him forever. And why? Even because God alone could teach us these things, which the hearts of men or Angels otherwise could never have conceived.
