The blessings put us in a historical perspective. These blessings, and by extension Rosh Hashanah, are all about relationships. We are striving to reestablish our relationship with Hashem. In recalling our deeds of the past year we realize we drifted away from Him. We must renew the ties.
Relationships are varied and complex.
This is true amongst ourselves, how much more so when relating to Hashem. In truth we do this daily, albeit in a less dramatic context. In the blessings surrounding the recitation of 'shema' we reveal a triple relationship with Hashem. In the first blessing we discuss God the Creator far beyond us. Then we explore our love relationship, both great and eternal, with Hashem.
