It is perhaps one of the finest principles with which the mind can be occupied, that our God desires that He may ever be learnt, in the variety of His perfections, by the need of His people. We have already met a striking illustration of this important principle, in the matter of Abram's conflict with the king of Sodom, in chapter xiv. There, when Abram was tempted by the offers of the enemy, he found relief in the apprehension of God's character as "the Most High God, the possessor of heaven and earth." The character of the communion into which Melchizedek led the soul of Abram was suited to the circumstances in which he stood. So is it exactly in this 17th chapter. Communion with God as "the Almighty" was the sole remedy for impatient anxiety as to the fulfillment of any promise. Now, when once the Lord exhibits Himself in His character of "Almighty," there can be no obstacle whatsoever to the outflow of His grace; for, when almighty power and almighty grace combine in behalf of the sinner, faith may count upon a rich and an abundant harvest. The promises, therefore, with which this chapter abounds are just such as we might have expected. "I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee. And I will establish my covenant between Me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee and to thy seed after thee. And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God." (xvii. 6-8.) Surely these are promises which _almighty grace_ alone could utter, _almighty power_ alone fulfill. The above promises stand connected with "the covenant of circumcision" which is specially important as looked at in connection with Abram's effort to obtain the seed otherwise than by the operations of God's own hand. It would be profitable to dwell for a little upon the doctrine of this covenant of circumcision but my design in taking up this history, is not by any means to handle it in a doctrinal way, but rather to draw from it some of those valuable principles of a decidedly practical tendency with which it so richly abounds; and therefore I pass rapidly over chapters xvi., xvii. which contain a mine of precious doctrinal truth quite sufficient to occupy a separate treatise.[4] [4] I would observe here that the doctrine of the Epistle to the Galatians stands intimately connected with chap. xvi., xvii., and I might add, the important doctrine of Israel's future restoration. We also get the doctrine of justification by faith fully illustrated in chap. xv.
