I don't know about all that pride and satan stuff, but I do have some thoughts. Sometimes they are contradictory to each other, my thoughts that is.
Being proud to be an American, is a lovely premise, if I thought that America was the be all and end all of perfect harmony, and believer of peace. This is tough because I am proud to be an American, based on the Declaration of Independence and the early vision of a perfect union. On the other hand, I am not proud of some actions that our country has taken. I keep forgetting that America is not a single entity. America is made up of many people, with many different takes on how this country should behave.
Re: Pride in my team. There have been many times when I have shaken my head at the followers of sports, who take pride in the fact that their team won. There is nothing wrong with being happy that a particular team has excelled. What bothers me is the shouting out, " We're number one" as if you personally had played the game. Then they go out and flip cars and destroy property in the name of team pride.
I am dismayed by parents that get so violent at children's baseball, football, basketball and other games all in the name of pride.
Pride is a good thing if it is not taken to the extreme. To feel good about one's self, one's child, one's team or one's country based on the accomplishment is ok. Saying that you are better than anybody else just because of the outcome of one or more contests, is distressing.
Competition is fine if it is to build one up. But competition geared towards tearing another down, is in my opinon, completely wrong. Think about it, in the olympics, participants have a few tries, and the best performance is the one that is taken, to advance to the next level. The same goes for baseball, football and basketball, to name a few. My point is, there is no reason to take pride in anything as it presents itself in the moment, for the next moment might produce totally different results. Enjoy the games for what they are, enjoy the reaching out to the world, but leave the pride out of it.
