We come to the end of this section that might best be described as the covenant ceremony where in the Lord impresses upon His people, His special nation, that they are to live in the land according to His commands, that they do so as a holy, consecrated nation, set apart for His covenant purposes, namely to prepare themselves for the coming Messiah by walking in step with the Lord and proclaiming and showing the nations that salvation comes in no other Name save the Messiah. Here at the end of the covenant renewal ceremony the Lord, having drug Israel across the law, promises that through the Messiah Israel would return having been given new hearts and restored souls. The law, as glorious, beautiful, and true as it is does not present us with a path to salvation, to a new heart, but instead is trains us to see our utter need to be given circumcised hearts and reborn souls - this God will do through the Christ.
