Endeavor to Preserve Spiritual Affections in the Heart

Endeavor to preserve and keep up lively, holy and spiritual affections in the heart, and suffer them not to cool…For such as your affections such must your thoughts be…Indeed, thoughts and affections are…the mutual causes of each other (Psalm 39:3); so that thoughts are the bellows that kindle and inflame affections; and then in they are inflamed, they cause thoughts to boil.

– Thomas Goodwin
