Quote from : Great Controversy: Between Christ and Satan Book

It is Satan's constant effort to misrepresent the character of God, the nature of sin, and the real issues at stake in the great controversy. His sophistry lessens the obligation of the divine law and gives men license to sin. At the same time he causes them to cherish false conceptions of God so that they regard Him with fear and hate rather than with love. The cruelty inherent in his own character is attributed to the Creator; it is embodied in systems of religion and expressed in modes of worship.
