2 Timothy 3:14-17

But you must continue with the things you have learned and found convincing. You know who taught you. Since childhood you have known the holy scriptures that help you to be wise in a way that leads to salvation through faith that is in Christ Jesus. Every scripture is inspired by God and is useful for teaching, for showing mistakes, for correcting, and for training character, so that the person who belongs to God can be equipped to do everything that is good.
