Psalm 39:6-7
Surely every man walks around like a shadow (in a charade); surely they make an uproar for nothing; each one builds up riches, not even knowing who will receive them. And now, Lord, for what do I expectantly wait? My hope (my confident expectation) is in You.

We need a purpose, and the right purpose, found through salvation through Jesus, fills up our spirits and souls. How often have those seeking riches, glory, and fame felt empty after attaining their goal? Without Jesus and salvation, we are like shadows of our true selves, always searching for the answer and never finding it, hallowed and empty.
