When I lead groups of people into wilderness areas we typically live in rain flys or tents for several days, sometimes a whole week. There are practical and theological reasons for doing this such as remembering our dependence on God in every way. It is significant for the Jews that the Festival of Booths (Leviticus 23) is annual and last for a week. One would not have the same experience if he were sleeping in the comforts of his home at night. The same is true for people enjoying the wilderness. There is something special about having extended time in makeshift accommodations that forges trust in God. Its actually a biblical idea to plan a weeklong camping trip with your family or friends! Don't feel guilty for taking time off to make this happen-it's biblical!
