"Now faith is the substance of things hoped for, the evidence of things not seen" Hebrews 11:1.
From my experience, faith is a combination of perfect confidence, utter humility, unconditional love and 100% responsibility.
This is the mechanics of creation. This is the womb of miracles.
When Peter stepped out of his storm-tossed boat onto the unsettled Sea of Galilee, he lost all reasonableness and stood on the liquid surface, defying gravity. For that moment, he was fearless
When I experienced the Miracle on Wilshire Boulevard in Los Angeles (1977), the feeling was one of invulnerability and utter love. When you take 100% responsibility, there is no room for you to be a victim. This is the natural state of the spiritual, true self (soul, Holy Ghost, child of God), within.
I also felt some of this when I found myself outside my physical body, in 1971. For a few moments, my consciousness was no longer dependent upon my body's brain. I tasted the "everlasting life" of spiritual consciousness that can continue no matter what happens to the physical body. These were a few moments without ego.
Some people live their lives with faith. They are prosperous, but also generous. They could give away a fortune one day and have a new one the next day, if they needed it. They are not attached to such things or fearful of losing them, because they have the feeling deep inside that abundance is always with them.
When I asked for "wide open spaces and smooth sailing all the way to my destination" on Wilshire Boulevard, bumper-to-bumper traffic disappeared from the center, Westbound lane within 5 seconds for a distance of 2 miles. Only recently did I realize that, logically, there was not enough room in the already crowded lanes, left and right, to "absorb" those additional cars.
Faith was "evidence" for the miracle being requested, before even knowing "how" it would be possible. But it is also "evidence" for the miracle even after being found physically impossible (like Peter walking on water, if only for a moment).
