“He that has doctrinal knowledge and speculation only, without affection, never is engaged in the business of religion.”
― Jonathan Edwards

“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.”
― Jonathan Edwards, The Life and Diary of David Brainerd

“Discipleship is not an offer that man makes to Christ.”
― Dietrich Bonhoeffer, The Cost of Discipleship

“When you find a chillness upon your souls, and that your former heat begins to abate, ply yourselves with warm clothes, get those good books that may acquaint you with such truths as may warm and affect your hearts.”
― Thomas Watson
