From Richard Baxter’s A Christian Directory Chapter 1, Part 1, Page 23,

“Holiness consisteth not in a mere forbearance of a sensual life, but principally in living unto God. The principle or heart of holiness is within, and consisteth in the love of God, and of his word, and ways, and servants, and honour, and interest in the world, and in the soul’s delight in God, and the word and ways of God, and in its inclination towards him, and desire after him, and care to please him, and lothness to offend him. The expression of it in our lives, consisteth in the constant, diligent exercise of this internal life, according to the directions of the word of God.”
