Martin Luther:“It is the true masterpiece of the New Testament, and the very purest Gospel, which is well worth and deserving that a Christian ... should not only learn it by heart, word for word, but also that he should daily deal with it as the daily bread of men’s souls. For it can never be too much or too well read or studied; and the more it is handled the more precious it becomes, and the better it tastes.”
John Calvin:“When anyone gains a knowledge of this [book], he has an entrance opened to him to all the most hidden treasures of Scripture.”
Arno Gaebelein:“Even if we have grasped the great doctrines of salvation as revealed in this [book] it is needful that we go over them again and again…No Christian can enjoy the Gospel and know true deliverance unless he knows the precious arguments of the first eight chapters of this [book].”
