2 Timothy 3:14-17

But as for you, continue in the truths that you were taught and firmly believe. You know who your teachers were, and you remember that ever since you were a child, you have known the Holy Scriptures, which are able to give you the wisdom that leads to salvation through faith in Christ Jesus. All Scripture is inspired by God and is useful for teaching the truth, rebuking error, correcting faults, and giving instruction for right living, so that the person who serves God may be fully qualified and equipped to do every kind of good deed.
