My unsolicited opinion on the Human Power of Faith:
What we consider to be Matter is actually 99.9999999% empty space, because that's how far we can zoom in today. What we consider to be real, or solid is just energy interacting with the energy bodies that our observer operates

Because everything is Energy, it all vibrates within a spectrum of frequencies. Your body is a frequency created from all of the frequencies within it. Changing one frequency, like the feeling of despair into joy, changes your bodies overall frequency.

Resonance occurs when an object emits a strong frequency and causes objects around it to vibrate in unison, aligning their vibration with the object emitting the strongest frequency. Strong Faith is like this strong frequency which causes resonance.

Faith, in my estimation, works by creating in your mind the future that you desire, and then amplifying that frequency alone, knowing that in the future, all of the energy in the universe will resonate with that frequency you are tuned to and produce exactly what you imagine.
