Indeed, thoughts and affections are sibi mutuo causae—the mutual causes of each other: “Whilst I mused, the fire burned” (Psalm 39:3); so that thoughts are the bellows that kindle and inflame affections; and then if they are inflamed, they cause thoughts to boil; therefore men newly converted to God, having new and strong affections, can with more pleasure think of God than any.
–Thomas Goodwin
