Here is an outstanding devotional note from Octavius Winslow, found in Go and Tell Jesus (page 9 in the edition I’m reading).
Dear reader, let the chief object of your study be to know the Lord Jesus. It may be in the region of your sinfulness, emptiness, weakness, and foolishness that you learn Him — nevertheless, however humiliating the school, slow the progress, and limited the attainment, count every fresh step you make in a personal acquaintance with the Lord Jesus as a nobler triumph, and as bringing you into the possession of more real wealth than were the whole arena of human knowledge and science mastered, and its untold treasures poured at your feet. When adversity comes, when death approaches, when eternity unveils — oh! how indescribably valuable, how inconceivably precious will then be one faith’s touch, one faith’s glimpse of a crucified and risen Saviour! All other attainments then vanish, and the only knowledge that abides, soothes, and comforts, is a heart-felt acquaintance with the sublimest fact of the Gospel, that Christ Jesus came into the world to save sinners.
