Faith is simply the product of your attention. Or, faith equals attention. The measure of your faith is the degree to which you can believe. Believing is an act of the will, a choice. Deciding is the essence of every act of will. To decide is to cut off other paths, investing no further faith/attention into other possibilities. Fear is attention given to worry-inspired thoughts. Faith in the opposite direction. Negative faith. Faith put into fearful futures creates footholds for malicious spirits, literally doing your enemy's work. This is why worrying is worse than nothing. Be nothing and let the spirit show you the way out. Be nothing by letting rational thought run its course into silence, then listening to the peace-inspired thoughts. Be nothing by recognizing the ego, remembering neither past nor future exist. There is only now.
