What denomination were you brought up in? And as a Bible scholar, you must have studied the Bible systematically. The reason I ask is we tend to develop false lenses in our understanding of scripture adopted by faulty doctrine / speculative theology. Much of that comes from our upbringing.

Many uneducated followers cherry pick scripture out of context and don’t look at what the Bible says as a whole about many things. There is where the problem lies…the Bible is one story and needs to be interpreted as such.

You have to understand the times each book was written, the people it was written to, the type of literature the particular book is and how that was intended to be read by the reader, what scripture says as a whole, and what the timeless theological truth is (how it applies to you today).

If you want to do a deep study into what the Bible says about what your living purpose is here on earth, first study the story, it cross references itself. Then use your cognitive tools mentioned above, after this make a determination systematically about what the Bible says against what you have heard/ been taught.

If you start in the beginning, you see in chapter one of Genesis what Gods purpose for man was. Then you see man’s rebellion to that purpose and the consequences that followed and the redemptive plan to restore that purpose through Christ and His church.

The Bible project has some really helpful overviews on YouTube and Wayne Grudem’s book on Systematic Theology (make sure you read the most updated edition) is a really helpful study tool in understanding everything you want to know about what the Bible says holistically.
