Don't think in terms of comfort; think in terms of freedom. Don't think in terms of safety, think in terms of being more alive. And the only way to be more alive is to live dangerously, is to risk, is to go on an adventure. And the greatest adventure is not going to the moon - the greatest adventure is going to your own innermost core.
The appetite for adventure and risk is not exclusive to young Christians. In face, it seems to be a fundamental yearning, knitted into the fabric of the human soul.
Life is perpetually creative because it contains in itself that surplus which ever overflows the boundaries of the immediate time and space, restlessly pursuing its adventure of expression in the varied forms of self-realization.
