The Love of G-d

Fearing G-d, without which man cannot merit holiness or purity, is itself a prerequisite to loving Him, the second stage of man's spiritual growth as he proceeds to accept upon himself the yoke of Heaven.

Loving G-d is a more exalted stage, as our sages said, (Sotah 31a), "One motivated by love for G-d is greater than one motivated by fear."

Fear ensures man's separating himself from evil, making it infinitely easier for him later on to attain reward.

As King David said, "Turn away from evil and do good" (Psalms 34:15). Fear of G-d distances man from evil, whereas love of G-d ensures that he will do good, out of desire and craving for G-d and His commandments.
