Greatness: A hero flying through space, or a butterfly outside our window?

Greatness.
It's night. The world is preparing for slumber. Unsuspected by everyone, a meteor is finding its way to Earth. To those few outside gazing at the stars it seems a comet, perhaps a shooting star. Some take one last look at this beautiful sight, then go inside. Others watch, at first in awe and wonder, but soon it turns to fear and horror as they realize the true nature of the "shooting star." They have mere minutes before it hits Earth and destroys it. But what's this? Our hero flies through the sky catching the meteor before it hits Earth and hurls it back into space.
Greatness.
He was pushed through the streets. While he deserved praise, love, kindness; he got dirty looks, hissed at, spat upon. While he should have gotten a crown of gold, he got one of thorns. He was placed upon a cross for all to see. While he should have had people crying at his feet, he got laughter and mockery. He died that we might live.
Greatness.
She sits in her rocker everyday. It's always the same. Her grey hair sways gently each time the rocker goes back and forth. Suddenly: a knock. She hobbles to the door, her thoughts racing to try to remember who she was supposed to be expecting. A young girl with a bright smile greets her. She was invited inside and together they talked for quite some time. The old lady was sad when the girl had to leave. It had been a real joy to have talked to her. People didn't come around often just to visit.
Greatness.
So what is greatness? Is it the hero that saves the day? Is it Christ, who died to save us all? Is it the girl that took time to visit someone in need? Greatness, to me, doesn't have to be a hero that saves everyone and whose deeds will be known throughout the world forever more. It can be someone, like this girl, who visited the old lady. Someone that does a small, simple thing that will be know by none but the old lady, and even she might forget it soon due to old age. Greatness is an act that will affect someone for the better, even if it's just one person. It doesn't even have to be a person for it to be greatness. It can be a performance, it can be a piece of art, it can be a butterfly outside your window that lifts your spirits. It has endless possibilities. It is Greatness.
