Faith is a mental attitude that is so convinced of its own idea - which so completely accepts it - that any contradiction is unthinkable and impossible.
The intellect is a cold thing and a merely intellectual idea will never stimulate thought in the same manner that a spiritual idea does.
Wait for the idea. It may not come at first, but you must be patient, never doubting, waiting in faith. It will come.
When we conceive a new idea we are thinking directly from the creativity of God.
