Knowledge is the accumulation of information which is given conceptual context in relation to other information. A complex web of information you might say. If information is sugar, flour, egg, and milk, knowledge is cake.
Belief is a form of knowledge that presupposes: "I believe I can have cake if I have sugar, flour, egg, and milk."
Even if no cake yet exists, belief that there can be a cake is justified by the information available. Probability based on material evidence.
Faith is a broader spectrum of belief. It deals only in possibility, not a narrower probability. As we all know, anything is possible (hypothetically speaking). There are no realistic parameters for possibility. And definitely no standard of evidence.
Faith is like having sugar and imagining that is all you need to make cake. Obviously not very realistic.
