But man may or may not fulfill his responsibility toward God - When men do accomplish their responsibility, God's plan comes to be concretely reflected in history and restoration progresses. But when men fail to fulfill their responsible part, God's plan for that time is frustrated, and Satan's will comes to be reflected in history instead. Thus, man can accomplish or fail his responsibility.
The reason human history appears as nothing but a constant reenactment of sinful history with the prospect of an ideal world seemingly so distant is not because God is impotent or not absolute, but because so few men accomplished their portion of responsibility to fulfill God's providence.
