“The foundation of all holy affections is in moral excellence and the beauty of holiness. There is a love of holiness for its own sake that inclines people to practice holiness. Holiness is thus the main business that excites, draws, and governs all gracious affections. No wonder then that all such affections tend to holiness, for men will be untied to and possessed by that which they love and desire. And what has been observed of the divine teaching and leading of the Spirit of God in gracious affections will show a tendency toward a universal, holy practice. The Holy Spirit gives the soul a natural relish for the sweetness of what is holy and for everything that is holy as it comes into view. He also intensifies a dislike and disgust of everything that is unholy.” J. Edwards

Edwards is not really talking about outward performance but an inward desire. He is saying that a christian grows in holiness as he desires the spiritual food more and more. In Psalm 27 the Psalmist talks about this one desire which overcomes every adversity on this earth. The Psalmist begins the Psalm with declaring victory in his occupation , which is war...then he goes into his relationships to people from those who are distant friends to his most cherished relationships.
Whatever opposition he faces in these corrupted relationships is overcome by this one desire..".I am confident of this that I will see the goodness of the Lord in the land of the living." This is another way of saying that this new desire is saying in the Psalmist... "Seek the Lord"...and his desire responds... "His face will I seek." He waits patiently knowing that all of the work of salvation has been gifted to him and is experienced on this earth in the land of the living which the Psalmist envisions as going on into eternity. The image of Christ overpowers all other images.
