We cannot sit back and expect to be spoon fed holiness. It is possible to sit (or stand, but especially while seated) in Church all of our life and not have learned one thing about holiness, if we are not willing to struggle and to suffer! Christ shows us the way, because He suffered voluntarily, for no good reason, just as we must do. “You could have no power at all against Me unless it had been given you from above.” Which means that He suffered willingly.

So how is it possible that we can attend church services all of our lives, and receive communion regularly, yet be largely clueless regarding our sole purpose as Orthodox Christians? We all know that this is not an uncommon phenomenon.
