Faith is the confident belief or trust in the truth or trustworthiness of a person, idea, or thing.  Faith can also be an expectation as well.   Jesus, in the bible performed many miracles and healings and attributed them to his faith and the faith of others.  In the bible Jesus says,I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, "Move from here to there" and it will move.
Matthew 17:20

 Matt 21:22: "And all things, whatsoever ye shall ask in prayer, believing, ye shall receive." (ASV)

If you can believe, all things are possible to him who believeth.
Mark 9:23

Was these bibilical teachings relaying information about the nature of the universe and the power of faith and belief as the tools used for manifestation.  

Given what we know about quantum physics, a universe made up of entirely energy, conscious enegy, that is spirit; we live in a conscious self aware universe that is in us and outside us, that interacts with us.  We are co-creators moving forwards of the future.  In a fractal universe of infinite expansion and infinite growth towards infinite complexity, faith is the key to manifesting  that which we want to see in life.  Simple manifestation may be manifesting what u want to have for dinner, or what kind of life you want ie, job, family, house etc.  However, is it possible that unwavering faith can create much more than this.  Can our intention effect the physical world around us. It can, mind power and powerful intent can speed up the healing processes of the body.  It has been measure that sending positive thoughts and energy to others records positive and healthy feedback in those recieving the positive energy.

Jesus said to him, "Receive your sight; your faith has healed you." Luke 18:42

The universe, our bodies, the people around us, responds to our intentions.  If our intention are backed by unwavering faith, the heavens and the earth will accomdate your desires.  This was the teaching that Jesus was trying to impart to humanity about faith.  We are made in the image of the creator, in a fractal universe we are a microcosm of the macrocosm.  We hold within us the infinite powers of the universe.  Through our faith we can recieve anything we ask for.  We can heal and create in this word and exercise our will to manifest as we desire as long as it is harmonious with heaven and earth.  

Faith, intention and belief is something that has to be embraced by the totality of your being not just your limited conscious mind, but also your conscious mind, and the superconsciousness that you share with the everyone and everything.  The human mind is very powerful, faith consolidates the power of your being.  Faith and belief slowly crystalize and molds the future which is constantly in flux towards the manifestation of its intent.  The stronger your faith the faster the manifestation.  So believe in yourself and believe in others, and have faith in the universe and in yourself.
