We have understood that it is because of the purpose of our Creator that we exist. We are not existing for our purpose. The purpose of God for our lives is what we must fulfill. We must fulfill the purpose of God. No man living should live for his or herself. If we try to live for ourselves we will fail. We should live for the one who created us.
The features of a creature determines why it was created and the purpose for which it was created. The musical instruments which have features for making melodious sounds was created for the purpose of making music. We are created for a specific purpose which is what we can see by the features of our body.
We we're created for good works. If you consider the parts of our body, you will discover that it was for good works that we were created. Our hands are succulents and tender so that they can give care. We do not have claws like the carnivores. So, we were not created to kill and maim other lives. God created us for good works.
