2 Timothy 3:14-17

But thou , abide in those things which thou hast learned, and of which thou hast been fully persuaded, knowing of whom thou hast learned them; and that from a child thou hast known the sacred letters, which are able to make thee wise unto salvation, through faith which is in Christ Jesus. Every scripture is divinely inspired, and profitable for teaching, for conviction, for correction, for instruction in righteousness; that the man of God may be complete, fully fitted to every good work.
