The creator is the one who determines how his creation will be used or his purpose. The answer is that he has no decision to make but just to exist and live according to his purpose.
The reason why it exists as the answer is because of the one who made it, made it for his purpose and without that purpose there is nothing can be left. We may have our desires and plans but there is one important reason why this can only exist if we trace it to the one
that created us.
If we are not created then we might not have to become whatever we should be anticipating ourselves for. We can have good dreams or visions for ourselves but it is good to keep aspiring for more greater things. But whenever we are doing that let us remember that we are not the one that is creating us.
It is God that determines our purpose here on earth. Sometimes we are created to fulfill some certain kind of purpose. So many people in the world are living the lives that consider the purpose of God. God has created them for. So that is why so many people refuse to submit themselves and obey common God. They want to live on their own way which always go against their will.
We must not live a life of disobedience. We must live according to the life of the one who has created us. We must submit to ourselves, live according to his purpose and fulfill his purpose.
