Sometimes we look at all the problems in our world, and wish that there were superheroes to save the day. With all the evil, we often find ourselves thinking "why can't someone just swoop in and fix this all?" It would be nice to have those heroes, but we have to make the best with what we have. Even without superheroes, we can make the world better.
The best way to do this is the same way the Avengers do it: They work together to solve the problems going on, and we can do the same thing. If we all join together, united in our cause, we can change the world. But, this is best done when we all have the same goal in mind. Never mind silly things that label us. Who cares what music we listen to, what sports we like, or if we even like sports, what political views we have, where we're from, or what we look like. Those things don't matter, and amount to nothing in an eternal perspective. We should all have the same vision, and all work together to accomplish it. United we stand, divided we fall. We need to all do our part to overcome the evils of this world, and make it the world it should be. Besides, we have God as our leader... He's a better than Nick Fury. If the Avengers can do it, so can we!
