The human mind

Have you ever stopped to wonder and marvel at the incredible strength of the human mind?
I was watching a reality show over my relaxing weekend where a girl believed she was pregnant. She was late for her period, and she began to have morning sickness. She even tested positive on a pregnancy test. A few days later, she got her period and everything came to a halt.
In another movie, a little girl played by Brittany Murphy (God rest her soul) has been in one psych hospital after another for multiple diagnoses and disorders. Her issue of biggest attention is her mutism and tendency to resort back to the little girl who cannot communicate with adults. Once her secret is revealed, however, her "disorder" all but disappears.
Movies? Yes. But real nonetheless. The human brain has been known to 'create' illnesses and disorders, even beliefs and experiences, by the sheer power of the imagination and belief system--convincing themselves that events have happened that in reality never occurred. That situations are real but in reality were never experienced. That people exist who do not. If one could master this, well, wow.... Just THINK of what possibilities would lie ahead!
I wonder if this is the type of faith that God asks us to have. The faith that would allow us to walk on water, to move mountains, to save. A sobering thought. All it takes is the direction of our brains and the pure focus on the focal point. If mere human beings can produce reality out of thought, what more could we do if that focus were where it belonged? What if our focus were so entranced on God and His desires for creation and the world that we could will miracles into action to bring others closer to Christ?
Religion aside, I cannot fathom to what extent the human mind could travel given it's strength when all focused on a single area. It's unfortunate that the world offers so many distractors at every turning point that the people who have acquired the ability to train and focus their brain down to a single microscopic point are considered to have a disorder.......
