2 Timothy 3:14-17
The Primacy of Scripture - Contemporary Service

14 But as for you, continue in what you have learned and firmly believed, knowing from whom you learned it 15 and how from childhood you have known sacred writings that are able to instruct you for salvation through faith in Christ Jesus. 16 All scripture is inspired by God and is[a] useful for teaching, for reproof, for correction, and for training in righteousness, 17 so that the person of God may be proficient, equipped for every good work.
