Deuteronomy 14:21

Verse 21. The spiritual man shall not appropriate or conjoin to his new life given to him from heaven anything which is void of the true regenerate life that comes from the Lord; he shall relegate it to what is not spiritual within him, that it may be conjoined to those external things within him which respect this life only; or he shall altogether alienate it from the soul: for the spiritual man is pure by receiving only what proceeds from the Divine Love and Wisdom. The innocence of true wisdom, which consists in acknowledging that all things good and true are from the Lord alone, must not be conjoined to the innocence of ignorance, which imagines there is somewhat good and true proceeding from the natural heart of man. (Arcana Coelestia 9301).
