"Study to divide the word of truth?" That's not the ultimate purpose of studying the word. The purpose is to do it. This rhymes with all the related points of scripture, including the OT, that culminates into the final conclusion of Ecclessiastics: Fear God and keep his commandments. Studying is not the purpose of study nor is it an end to itself.

edit: an example of one of these "points" is Joshua 22:5.
