2 Timothy 3:14-17

But continue thou in those things which thou hast learned, and which have been committed to thee: knowing of whom thou hast learned them; And because from thy infancy thou hast known the holy scriptures, which can instruct thee to salvation, by the faith which is in Christ Jesus. All scripture, inspired of God, is profitable to teach, to reprove, to correct, to instruct in justice, That the man of God may be perfect, furnished to every good work.
