There is a story which originated from G.K. Chesterton that told of a father and his three children, ages 3, 6 and 9.
One night, as he was going room-to-room putting his kids to bed, he told each - the same story.
"...and then, I got up and walked to the door.." said the father, finishing up the tale to his 3-year-old.
The boy's eyes were large and his mouth wide open.
He finished up the story - and then walked into his 6-year-old daughter's room.
"...and then, I got up and walked to the door.."
The girls eyes were intently fixed on her father.
"..and opened it..."
"Oh no! Watch out!" the daughter exclaimed, terrified.
He finished the story, tucked his daughter in bed and shut off the lights.
Lastly, the father walked into his 9-year-olds bedroom and began to weave his tale.
"...and then, I got up and walked to the door...and opened it..."
The boy smiled.
"...and behind the door...was...a lion!"
The boy's eye lit up and his jaw dropped.
"Oh, wow!" he exclaimed.
Chesterton's aim of relaying this story was to make an important point: as we get older, our heart seems to need bigger and bigger things to fill it. No longer is it just fulfilled with the big blue ball rolling on the ground. It longs for something more profound.
Our hearts were made to be in awe. And the only thing big enough to fill them is God.
"Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways!" May we find our joy in seeking Your endless depths and riches! Only You are big enough to fill our deepest longings, O God!
