Yes, like everywhere else in the world, there are phonies in churches. There are cliques and there is backstabbing going on. But when you can look beyond yourself a little bit, you are able to see these things as opportunities for ministry rather than taking them personally.
There is a popular song out there right now that illustrates the self-focused attitude. I don't know the artist or all of the lyrics, but here is a couple of lines:
"Because of you, I never strayed too far from the sidewalk,
Because of you, I always played real close so I won't get hurt..."
The singer goes on to lament that her life is ruined because her father was overbearing, overprotective and cold. Well okay lady, you had a hard childhood, but it is time to go on. There is a world of other people out there who could use your unique talents whatever they may be. The attitude exemplified in this song is encouraged in our culture. If you don't have a healthy "self-esteem" you may as well give up.
A great irony in this episode is that the essence of Christianity is "other-centeredness" or simply love. Perhaps that has something to do with why the shooter hated Christians. Their very essence was threateningly alien to him.
Oh and by the way, this outward looking attitude would also help in toning down some of the high spirited posts I see on this very thread. Read my tagline.
God can bring good out of something bad and we see this often in accomplished adults who had problem childhoods.
