John 14:26 (NLT2) But when the Father sends the Advocate as my representative—that is, the Holy Spirit—he will teach you everything and will remind you of everything I have told you.
When the Spirit illuminates the heart, then a part of the man sees which never saw before; a part of him knows which never knew before, and that with a kind of knowing which the most acute thinker cannot imitate. He knows now in a deep and authoritative way, and what he knows needs no reasoned proof. His experience of knowing is above reason, immediate, perfectly convincing and inwardly satisfying. A. W. Tozer (1897-1963)
