somehow the ants don't seem to mind

There's a comedian named Brian Regan who wonders why ants don't freak out when their nice little hill gets knocked over. Why not even one of them sits down and says "I'm not building THAT again. He's just gonna knock it over."

Their life's work is in shambles and they don't even stop to mourn it's passing.
The cat snoozing on the couch doesn't meditate on the fact that his life is seemingly without meaning?
How did man get this sense of lasting permanence and desire for purpose?
Not from experience. Nothing in this world speaks of these ideals. Everything points to shaky foundations that can't be leaned on. To cars that need constant repairing. To markets that fluctuate. To storms and disease that destroy. To families that break apart.
Then, why do we care if our little world falls to pieces?
We find that God has placed eternity in our hearts. That He has placed in us a desire for what never fades away, for what cannot be corrupted or defiled, and for What is infinitely more Good than what we could ever be.
Come Lord Jesus!
