The type of faith that does not recognize or understand the principles that lie behind the manifestations from substance is often referred to as "blind faith."
"Understanding faith" is when one recognizes the principles, the immutable laws, that exist within God. An example of an immutable law is that, regardless of what you believe, you cannot put one and one together without having two. In other words, "our knowing it or not knowing it does not change the truth."
Whether you have blind or understanding faith, intuition is the receiving end of the channel connecting each of us to God, to all good. How much we are willing to accept in our lives from substance is how much intuition we choose to receive. "As you believe, it is done unto you." Your level of faith determines what is able to flow to you from Spirit.
How Much Faith Is Enough?
Scriptures such as "Without faith, it is impossible to be well-pleasing unto Him," can spark questions in our minds about whether we can possibly have enough faith or can draw out of God-substance something we've never been able to manifest before. With this attitude, it is easy to see why people would resort to relying on intellectual proof.
Cady stresses that faith "takes hold of the substance of the thing hoped for, and brings into evidence , or visibility, the things not seen." Understanding faith is faith based on principle. Just as you always know that two is the result of putting one and one together, you always know that he who does "not doubt in his heart, but shall believe that what he saith cometh to pass; he shall have it." [Mark 11:23]
Having understanding faith resolves doubts because of the belief in immutable laws. Being unchangeable, these principles are not fickle. When Jesus said, "Ask, and ye shall receive," he didn't conclude that statement with if you are sufficient enough. Whatever you believe with both your thoughts and your feelings ,that is, what you can accept for yourself, then when you ask, you shall receive.
Where Does Desire Originate?
Have you ever wondered from where a desire for good comes? Cady says, "Desire in the heart is always God tapping at the door of your consciousness with His infinite supply—a supply that is forever useless unless there be demand for it." So God is always seeking to express good in your life.
Some have asked, "What if I desire something that belongs to my neighbor?" In Truth, you do not actually desire what belongs to someone else. You are simply desiring what it represents, whether it is love or peace of mind, etc. You cannot receive someone else's good nor can they receive yours.
The Bottom Line
Providentially, as Emerson points out, a man who knows the law cannot escape from his good. The bottom line is that the life you experience is the measure of your faith.
