2 Timothy 3:14-17

But you must hold onto the things you've learned and are convinced are true. You know who taught you. From your childhood you've known the holy Scriptures which can give you understanding for salvation by trusting in Christ Jesus. All Scripture inspired by God is useful for teaching, for confronting what is wrong, for setting us straight, and for telling us what is right. This is how God provides a thorough preparation for those who work for him to accomplish all that's good.
