All in The Wilderness

How many times have we been led by the Spirit into a wilderness of some type, and to what end were we led there? Jesus was led into the wilderness to be tempted by Satan, but we really don’t know what went on there during those forty days prior to the three temptations except that he fasted, and became hungry. What we do know is that at the end of His time in the wilderness He successfully faced the temptations that we are so familiar with. So what is it that takes 40 days to accomplish that can prepare us to face such trials?
