Day in and day out, we are constantly on an existential search for answers to this question: "What gives my life meaning"?
It is important to note that this longing for something to satisfy us is actual a normal response that speaks to our broken human condition. We long for something more. And that something more is beyond any temporary pleasure that only this world can give. That something more is eternal. That something more is God.
And all things apart from Him are mere chasings after a wind that you will never be able to catch in your lifetime.
