In contrast, when a group of tourists went mountain climbing in Switzerland they all fastened themselves together to a line. As they were ascending one of climbers slipped. He would have fallen to his death on the rocks below but was saved because he was connected to a lifeline. The other people pulled him to safety.
After reading about these mountain climbers, it occurred to me that some Christians are like the man who went off by himself. They might watch evangelists on TV and listen to Christian radio, but they aren't connected to other believers through a relationship with them. Sooner or later they will fall and no one will be there to catch them.
However, other believers are like the team that was connected together with a lifeline. They spend time together in prayer and fellowship so that they know what's going on in each other's lives. If one of them falls, the others are there to hold the person up. That's why Hebrews 10:25 says to "not forsake the assembling of ourselves together, as is the habit of some."
Sure, it's easier to just withdraw and not get involved in other's lives. But God didn't design you, or call you, to be independent. We are a part of Christ's body. We need each other. Which kind of mountain climber are you?
