Passage
And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.
And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.
Deuteronomy 30:4 If any of thine be driven out unto the outmost parts of heaven, from thence will the LORD thy God gather thee, and from thence will he fetch thee:
Deuteronomy 30:5 And the LORD thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers.
Deuteronomy 30:6 And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.
Deuteronomy 30:7 And the LORD thy God will put all these curses upon thine enemies, and on them that hate thee, which persecuted thee.
Deuteronomy 30:8 And thou shalt return and obey the voice of the LORD, and do all his commandments which I command thee this day.
The verse centers on "lord", "circumcise", "thine", "heart", "seed", and "love". It is saying that the verse draws attention to "lord" and "circumcise", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "And the LORD thy God will bring..." into verse 7's "And the LORD thy God will put...", so "lord" and "circumcise" belong inside that flow. In Deuteronomy context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "lord" and "circumcise" with trust shaped by these words, not by a vague optimism outside the passage.
