The Conditions for Restoration and Blessing

301 When all these things have happened to you, the blessings and the curses that I have set before you, if you call them to mind among all the nations where the Lord your God has driven you, 2 and return to the Lord your God, and you and your children obey him with all your heart and with all your soul, just as I am commanding you today, 3 then the Lord your God will restore your fortunes and have compassion on you, gathering you again from all the peoples among whom the Lord your God has scattered you. 4 Even if you are exiled to the ends of the world, from there the Lord your God will gather you, and from there he will bring you back. 5 The Lord your God will bring you into the land that your ancestors possessed, and you will possess it; he will make you more prosperous and numerous than your ancestors. 6 Moreover, the Lord your God will circumcise your heart and the heart of your descendants, so that you will love the Lord your God with all your heart and with all your soul, in order that you may live. 7 The Lord your God will put all these curses on your enemies and on the adversaries who took advantage of you. 8 Then you shall again obey the Lord, observing all his commandments that I am commanding you today, 9 and the Lord your God will make you abundantly prosperous in all your undertakings, in the fruit of your body, in the fruit of your livestock, and in the fruit of your soil. For the Lord will again take delight in prospering you, just as he delighted in prospering your ancestors, 10 when you obey the Lord your God by observing his commandments and decrees that are written in this book of the law, because you turn to the Lord your God with all your heart and with all your soul.

Commentary on Deuteronomy 30:1-10

(Read Deuteronomy 30:1-10)

In this chapter is a plain intimation of the mercy God has in store for Israel in the latter days. This passage refers to the prophetic warnings of the last two chapters, which have been mainly fulfilled in the destruction of Jerusalem by the Romans, and in their dispersion to the present day; and there can be no doubt that the prophetic promise contained in these verses yet remain to come to pass. The Jewish nation shall in some future period, perhaps not very distant, be converted to the faith of Christ; and, many think, again settled in the land of Canaan. The language here used is in a great measure absolute promises; not merely a conditional engagement, but declaring an event assuredly to take place. For the Lord himself here engages to "circumcise their hearts;" and when regenerating grace has removed corrupt nature, and Divine love has supplanted the love of sin, they certainly will reflect, repent, return to God, and obey him; and he will rejoice in doing them good. The change that will be wrought upon them will not be only outward, or consisting in mere opinions; it will reach to their souls. It will produce in them an utter hatred of all sin, and a fervent love to God, as their reconciled God in Christ Jesus; they will love him with all their hearts, and with all their soul. They are very far from this state of mind at present, but so were the murderers of the Lord Jesus, on the day of Pentecost; who yet in one hour were converted unto God. So shall it be in the day of God's power; a nation shall be born in a day; the Lord will hasten it in his time. As a conditional promise this passage belongs to all persons and all people, not to Israel only; it assures us that the greatest sinners, if they repent and are converted, shall have their sins pardoned, and be restored to God's favour.
