2 Timothy 3:14-17 NIV

[14] But as for you, continue in what you have learned and have become convinced of, because you know those from whom you learned it, [15] and how from infancy you have known the Holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. [16] All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, [17] so that the servant of God may be thoroughly equipped for every good work.
