If the heart be chiefly and directly fixed on God, and the soul engaged to glorify him, some degree of religious affection will be the effect and attendant of it. But to seek after affection directly and chiefly; to have the heart principally set upon that; is to place it in the room of God and his glory. If it be sought, that others may take notice of it, and admire us for our spirituality and forwardness in religion, it is then damnable pride; if for the sake of feeling the pleasure of being affected, it is then idolatry and self-gratification.
-David Brainerd, Diary
David Brainerd (1718 – 1747 AD) was an American missionary to the Native Americans who had a particularly fruitful ministry among the Delaware Indians of New Jersey. During his short life he was beset by many difficulties. As a result, his biography has become a source of inspiration and encouragement to many Christians, including missionaries such as William Carey and Jim Elliot, and Brainerd’s cousin, the Second Great Awakening evangelist James Brainerd Taylor.
