 Duty, because what they do is they equate duty to the works of the law. That is baloney. That is unscriptural. You do what you do because you're saved. You do what you do because to whom much is forgiven loves much, right? So out of gratitude, we obey the Lord because we love him for what he did through his son, Jesus Christ. That's what makes us Christians, 1126 of Acts.
