Purpose is more about the Creator has not worked or walked in purpose. If you make or you buy a thing for a purpose and the thing doesn't fulfill that purpose, it doesn't matter if the thing. It was useless. The latter part says, for thou has created all things for thy pleasure. They are and were created.
Every proper religion that exists, exists to answer those two questions. The first question is a question of purpose. The second question, is a question of purpose.
1. What is the meaning of my life here? and What if I die now, where am I going to?
2. If there's somebody I have to be accountable to am I doing the right thing?
One of the things Jesus came to do was to give your life a purpose He came to give your life meaning.
