Sometimes, you have to get to a point of total frustration before you'll be ready to make a big change. Don't wait for what anyone else should do but hasn't yet and likely won't. Instead, look for what is up to you and what you can do to change the situation for the better... even if it means walking away entirely.
Smile, it makes a world of difference. Dance, who knows when you won't be able to? Cry, holding those emotions inside is bad for you. Kiss, it's one of the most wonderful things in this world. Laugh, what's the point of hiding happiness? Frown, why not let them know you're unhappy? Apologize, you don't wanna lose friends right? Hug, there's no better feeling than being wrapped up close to someone you love. Live, because life is everything.
Life is about getting up out of your chair and doing something. It is about doing nothing. Making a mess. Moving your hand and your body. Leaving a mark. It is about doing. Action. Finishing. Experimenting. Trying something. Immersing. It is about absurdity. A creation. Evidence that you exist. Using materials. Destruction. It is about fun. Doing the opposite. Breaking the rules. It is about ideas. Getting dirty. Making mistakes. I'm going to ask you to make a mark and it's going to be messy. Don't worry about that. That's the point.
The good works that really matter require the help of heaven. And the help of heaven requires working past the point of fatigue so far that only the meek and lowly will keep going long enough. The Lord doesn't put us through this test just to give us a grade; he does it because the process will change us.
In most cases, obviously, soldiers fought because a government drafted them and gave them a rifle. At every point too, we see the role of nationalistic sentiment, commercial rivalries, and simple greed. But can we ever separate out such motives from the religious? Was that not also true of the medieval crusades?
