There must be opposition, or opposites, in all things. Bad is the absence of good. Darkness is the absence of light. Sorrow is the absence of joy. How could we ever understand warmth if we never experienced cold? God is the author or provider of light, life, truth, joy, and good. The adversary can provide only the opposites because he takes away. He can provide darkness (the absence of light), death (the absence of life), falsehood (the absence of truth), misery (the absence of joy), and evil (the absence of good). The devil actually provides nothing; he just sees to it that all who cooperate with him are devoid of the blessings that God does provide. The unrighteous may not be miserable according to their perspective, but they do not know real happiness.
