Holding back is usually just an excuse to do nothing—to live for self. Or to pay lip service to something. After all, saying it is as good as doing it, right? To actually do something means I'm committed to it—that I can't back out. I want my options! Leave that door open...I might need it some day! Never mind that it only brought me heartache and trouble! At least it was my decision! I certainly don't want to be labeled a fanatic! Unless, of course, it's something important like a football game or other sporting event. You know, the really important stuff...
No wonder the early church frowned on the gladiator games!
