This is most probably the meaning, but with the addition that he speaks of “earnestness” generally, not merely of active diligence. Their religion was too narrow in range. Care for the poor has sometimes been the piety of sluggish despondency and bigotry. But spiritual earnestness is the moral discipline that works hope, a hope that makes not ashamed, but leads men on to an assured confidence that the promise of God will be fulfilled, though now black clouds overspread their sky. An incentive to faith and endurance will be found in the example of all inheritors of God’s promise.[109] The Apostle is on the verge of anticipating the splendid record of the eleventh chapter. But he arrests himself, partly because, at the present stage of his argument, he can speak of faith only as the deep fountain of endurance. He cannot now describe it as the realisation and the proof of things unseen.[110] He wishes, moreover, to dwell on the oath made by God to Abraham. Even this, if not an anticipation of what is still to come, is at least a preparation of the reader for the distinction hereafter effectively handled between the high-priest made without an oath and the High-priest made with an oath. But, in the present section, the emphatic notion is that the promise made to Abraham is the same promise which the Apostle and his brethren wait to see fulfilled, and that the confirmation of the promise by oath to Abraham is still in force for their strong encouragement. It is true that Abraham received the fulfilment of the promise in his lifetime, but only in a lower form. The promise, like the Sabbath rest, has become more and still more elevated, profound, spiritual, with the long delay of God to make it good. It is equally true that the saints under the Old Testament received not the fulfilment of the promise in its highest meaning, and were not perfected apart from believers of after-ages,[111] God’s words never grow obsolete. They are never left behind by the Church. If they seem to pass away, they return laden with still choicer fruit. The coursing moon in the high heavens is never outstripped by the belated traveller. The hope of the Gospel is ever set before us. God swears to Abraham in the spring-time of the world that _we_, on whom the ends of the ages have come, may have a strong incentive to press onwards.
