I am reading through Isaiah currently (little by little, trying to learn and glean as much as I can) and not long ago read this verse:
"Everyone who is called by My name,
and whom I have created for My glory,
Whom I have formed,
even whom I have made."
This is just one little verse from a big book (and I recommend going and reading more of it!) but I think it has a pretty neat message. People wonder from time to time, "Why are we here?" , "What is life's purpose?" this verse pretty much takes care of that. We are here to bring glory to God. That is our life's purpose.
Now the question is: "Am I doing that?" and are you doing that?
