When I was in the marines, the training for commandos included cliff assaults. The theory was that a commando raid should be a surprise, done as quickly and as silently as possible on the area with the lightest defenses. The lightest defense is at the point where attack is least expected. More often than not, it was the cliffs.

We would come close to the cliff in our small boats and fire one rocket up through the darkness. Attached to the rocket was a grapnel. Attached to the grapnel was a light rope. When the rocket landed on top of the cliff, the grapnel would lie on the grass. We would then pull it back gently until it caught on something. We hoped it caught on something secure.

We had expert climbers. Those guys were like spiders. They would get out of the little boat onto the seaweed-strewn rocks, and scale those cliffs in the dark hanging onto this thin, little rope that was on the end of a grapnel they hoped was hanging onto something secure.

A bigger rope trailed behind them. Below, we held onto the rope. When the climber got on the top, he would secure the rope he'd taken up and then give two little tugs on it. The minute the two little tugs came, we jumped out of our boats, cold and wet on the waves and rocks. We would scale the cliffs. It was a hairy experience, except we had utter confidence in the one who'd gone before us. We had utter confidence in the security of the rope he had fastened for us.

You could imagine my delight when I discovered that Jesus is called "the one who has gone before," or in the Greek, the "prodromos." The prodromos was a person who headed a patrol in military maneuvers. He was the one who went ahead and made sure the way was open. I rejoice to tell you that many times we'd find ourselves totally secure on those cliffs because of the utter reliability of the skilled climber.
