@Cyracuz,
That's a problem with the word Faith, linguistically means one thing, spiritually it means something I can't describe.
Let me try another way. Let's take the knowledge you were talking about earlier, I have no knowledge of God, all my knowledge is of God's creation.
We can't really separate ourselves from that. We are not equipped to deal with infinity, or the lack of it for that matter.
When I use the term Faith, in a spiritual sense, I refer to the unknowable God, not the creation. Faith, in this sense, is not a destination, or an understanding, it is a direction, a willingness, a choice.
