“True sanctification, true growth in holiness, is internal. It will manifest itself on the outside; "The tree is known by its fruit" (Matt. 12:33). But the tree creates the fruit; the fruit does not create the tree. Edward Fisher, in his famous Puritan treatise on sanctification, explained that external conformity to rules without an internal reality fueling it is akin to watering every part of a tree except its roots and expecting it to grow. The internal realities of the Christian are what define true growth in Christ.”
