It is exceedingly sweet as Jonathan Edwards writes:
Holiness is a most beautiful, lovely thing. Men are apt to drink in strange notions of holiness from their childhood, as if it were a melancholy, morose, sour, and unpleasant thing: but there is nothing in it but what is sweet and ravishingly lovely... It is a divine beauty.
Indeed too many Christians have drank strange notions of holiness from their childhood and too many from the pulpits. O how often is the love of God pitted against his holiness as if holiness is an unloving thing, the stern side of God that makes him a kill joy.
It is the very opposite! God is set apart from us, from every being by his holiness namely that he has none of those qualities, yea those ugly qualities found in us.
So God calls us to walk in holiness here on earth so that we may experience the sweetness and happiness of life that comes from a pure heart. Blessed are the pure in heart for they shall see God. They shall see the radiance of God, the beauty of God, the essence of God and the loveliness of God.
Our hearts shall be ravished with heavenly joy when we choose to forsake our sins and live each day in holiness. And this daily holiness looks like love, joy, gentleness, peace, kindness, goodness, faithfulness and so on. Against such things there is no law!
