Reformed theology indeed insists that a real measure of freedom has been assigned to man by the Creator. But that freedom is not absolute and man is not autonomous. Our freedom is always and everywhere limited by God’s sovereignty. God is free and we are free. But God is more free than we are. When our freedom bumps against God’s sovereignty, our freedom must yield.
