Because we have these promises, dear friends, let us cleanse ourselves from everything that can defile our body or spirit. And let us work toward complete holiness because we fear God.
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. God uses it to prepare and equip his people to do every good work.
