2 Timothy 3:16-17

16All Scripture is God-breathed [given by divine inspiration] and is profitable for instruction, for conviction [of sin], for correction [of error and restoration to obedience], for training in righteousness [learning to live in conformity to God’s will, both publicly and privately—behaving honorably with personal integrity and moral courage];

17so that the man of God may be complete and proficient, outfitted and thoroughly equipped for every good work.
