Matthew Henry’s Concise Commentary
Deuteronomy 30:1-10 In this chapter is a plain intimation of the mercy God has in store for Israel (“for all person’s and all people, not to Isreal only” see below) in the latter days. The language here used is in a great measure an absolute promise; not merely a conditional engagement, but declaring an event assuredly to take place. For the Lord himself here engages to circumcise (remove all desire to sin, Webster’s 1828) from 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.

Ephesians !:3,4 (The New Testament in Modern Speech Richard Francis Weymouth)
“Blessed be the God and Father of our Lord Jesus Christ, who has crowned us with every spiritual blessing in the heavenly realms in Christ:even as, in His love, He chose us as His own in Christ before the creation of the world, that we might be holy and without blemish in His presence. (notes:”He chose us as His own” Literally ‘He chose us out (of the world)for Himself.)

What a wonderful assurance and promise from God as we pray about our world today. Thank you lesson writer for this beautiful and instructive lesson.
