2 Timothy 2:15; 2 Timothy 3:16-17

15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.

16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:

17 That the man of God may be perfect, throughly furnished unto all good works.
