Deuteronomy 4:15

Verse 15. It is necessary, therefore, to watch what passes in the soul with jealous care, for it was perceived that nothing from self which simulates good in externals is to be worshiped in the place of the pure goodness and truth which proceeds from the Lord's Humanity in that state in which the soul received illustration from the Lord, proceeding from the Divine Love, as to what is necessary for salvation.
