But what sin really is is not absolutely clear. Sin is to cast aside the will of God and to live according to one's own will, deserting that which is true and lawful in order to satisfy one's own desires, thinking thus to obtain happiness. Yet in so doing one does not obtain real happiness or enjoy true pleasure.
Sin has no individuality, so that no one can say of it that someone created it.
It is simply the name of a state or condition. There is only one Creator and He is good, and a good Creator could not have created a bad thing, for to do so would be against His very nature. And apart from the one Creator there is no other who could have created sin. Satan can only spoil that which has already been created, but he has not the power of creating anything. So sin is not a part of creation, nor has it independent existence such that it could be created.
