How does examination create tremendous emptiness in life?

I have found, it depends on what you are looking for. As the saying goes, nothing from nothing, leaves nothing.
There are many ways to examine ourselves, and you might ask, compared to what?
Compared to another person, could be a waste of time, since that other person is just as imperfect as you are.
When a product is purchased, we expect it to perform in a certain way, if not we go back to the manufacturer, for an explanation or refund.
Our manufacturer is God. His explanation is found in his word the Bible, with a guarantee. You can read it for yourself at John 17:3 where it says, "This means everlasting life, their coming to know you, the only true God, and the one whom you sent, Jesus Christ".
When we find out what God expects of us, then we know how we can function effectively, His purpose and how we fit in with it. Our lives will no longer feel empty, because we have a purpose.
