2 Timothy 3:14-16

But you must remain faithful to the things you have been taught. You know they are true, for you know you can trust those who taught you. You have been taught the holy Scriptures from childhood, and they have given you the wisdom to receive the salvation that comes by trusting in Christ Jesus. All Scripture is inspired by God and is useful to teach us what is true and to make us realize what is wrong in our lives. It corrects us when we are wrong and teaches us to do what is right.
