Solitude sounds like a death sentence to some people, particularly those who are energized by being around others. But for the introvert or contemplative, it is a release. Temperament aside, there may be something about the wilderness that favors the eye of God in ways we don't realize. Moses spent forty years in the wilderness. Paul spent three years in the desert, and Jesus forty days.
Solitude invites entry to the soul, a discipline that even the ancients knew unlocked the spirit.
Solitude is a place where the Creator can speak with less interruption. It was that for me. I took enough supplies so it would not be necessary to see another human for the duration. I wanted this to be a time for God to work on me, a thorough spiritual examination from head to toe. I resolved to fast the first three days for all the spiritual and physiological reasons, and I take it by faith that it was beneficial.
