Faith is the mind of Jesus Christ in us. It's the perfect interpretation of God's Word. Any true revelation of God's Word or true ministry will be according to the Bible from Genesis to Revelation.
Any word is a thought expressed.
God's Word is His thoughts, and He expresses them first-hand to a prophet. We all hear It second-hand as it were. But our understanding or faith comes to us personally from God, first-hand. Very few people have faith because they're content with a second-hand religion . Ministers and priests are just as guilty.
