2 Timothy
King James Version (KJV)

“Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.”
King James Version (KJV)
2:15 A workman that needeth not to be ashamed - Either of unfaithfulness or unskilfulness. Rightly dividing the word of truth - Duly explaining and applying the whole scripture, so as to give each hearer his due portion. But they that give one part of the gospel to all (the promises and comforts to unawakened, hardened, scoffing men) have real need to be ashamed.
2Ti 2:15 Study to shew thyself. To this end the utmost diligence must be used. Approved unto God. Such a preacher that his work will please the Heavenly Father. A workman that needeth not to be ashamed. Whose life and work are such as to honor Christ and the gospel. This requires a pure life as well as judicious work. Rightly dividing the word of truth. The Revised Version reads, "Handling aright". The Greek word "orthotomeo" means, literally, "cutting straight". The thought, probably, is to present the truth clearly, truthfully, without blunders, and with an exactness which cannot be gainsaid.
