“Do not say that you are the temple of the Lord, writes Jeremiah (cf. Jer. 7:4); nor should you say that faith alone in our Lord Jesus Christ can save you, for this is impossible unless you also acquire love for Him through your works.
As for faith by itself, ‘the devils also believe, and tremble’ (Jas. 2:19).”
