We run to comforts, not away from them. Why would we, or why should we proactively seek out times of less comfort?
God has done His greatest teaching, since the beginning of time, through time spent in the Wilderness. As Charles Spurgeon put it, "The wilderness was the Oxford and Cambridge for God’s students. There they went to the University, and He taught and trained them."
When the comforts of life are stripped away, the real us has a way of rising to the surface. Then, and only then, can we evaluate who or what we have placed as #1 in our life. If it is not God, we get to realign our priorities and place Him back on the throne. When we can pass the Wilderness test as Jesus did, then we can stop going back.
God desires for our lives to be solely focused on Him. He wants to help us rid our lives of those things that are not of Him. We get to choose whether we want to actively engage in this process or run from it until we run out of options.
The Wilderness is necessary. It has been necessary since the beginning. It remains necessary.
