6:13 {7} For when God made promise to Abraham, because he could swear by no greater, he sware by himself,
(7) Another encouragement, to push them onward because the hope of the inheritance is certain, if we continue to the end, for God has not only promised it, but also promised it with an oath.
6:13 For when God made promise to Abraham. The promises are absolutely sure. See how God confirmed his promise to Abraham! See Ge 22:15-18.
6:13 For - Ye have abundant encouragement, seeing no stronger promise could be made than that great promise which God made to Abraham, and in him to us.
6:11-20 The hope here meant, is a sure looking for good things promised, through those promises, with love, desire, and valuing of them. Hope has its degrees, as faith also. The promise of blessedness God has made to believers, is from God's eternal purpose, settled between the eternal Father, Son, and Spirit. These promises of God may safely be depended upon; for here we have two things which cannot change, the counsel and the oath of God, in which it is not possible for God to lie; it would be contrary to his nature as well as to his will. And as He cannot lie; the destruction of the unbeliever, and the salvation of the believer, are alike certain. Here observe, those to whom God has given full security of happiness, have a title to the promises by inheritance. The consolations of God are strong enough to support his people under their heaviest trials. Here is a refuge for all sinners who flee to the mercy of God, through the redemption of Christ, according to the covenant of grace, laying aside all other confidences. We are in this world as a ship at sea, tossed up and down, and in danger of being cast away. We need an anchor to keep us sure and steady. Gospel hope is our anchor in the storms of this world. It is sure and stedfast, or it could not keep us so. The free grace of God, the merits and mediation of Christ, and the powerful influences of his Spirit, are the grounds of this hope, and so it is a stedfast hope. Christ is the object and ground of the believer's hope. Let us therefore set our affections on things above, and wait patiently for his appearance, when we shall certainly appear with him in glory.
