My people perish from a lack of knowledge. - Hosea 4:6
(King James Version)
Indeed Christ is admonishing us to know Him more deeper. Not just letters from a book, or a mere doctrine, or just objectively. He wants us to seek the truth, and the only truth can be found in Christ. That's why christianity today has such a shallow understanding of Christ, to the point that they don't even touch the book of Revelations, where you will really have a clear picture of who the enemy is, and how he operates.
