He that has doctrinal knowledge and speculation only, without affection, never is engaged in the business of religion.
—Jonathan EdwardsIt is not an either/or situation. Edwards of all people had a vast, large, in-depth aptitude in knowledge; but that is not all he had. This doesn't mean our emotions will be "mountain top thrills" for 16 hours every day. But there will be a calm enduring love and joy in Jesus that is a result of His grace and not a cause or condition of His grace being conferred.
