People have always enjoyed the challenge of overcoming obstacles. When there's a wall they say can't be crossed or a mountain that can't be climbed there's always been someone there to prove the nay sayers wrong.
With CLYM, the focus is on the youth to take their relationship with Christ to the next level, go beyond themselves and CLYM higher. Just like mountain climbing, when the body reaches a certain elevation, it begins to feel uncomfortable and your body experiences discomfort.
To reach a new altitude in our relationship with God we too may experience discomfort but, as many mountain climbers will tell you, the view from the top is so, worth it.
