If we can bring ourselves, regardless of dogma, to believe in the equivalent of A.N. Whitehead's "process God," the next step would be a realization that through evolving together with us, God and humanity penetrate each other. That presumes the necessity of one integrating or completing the other, which further means that we are complicit with God in what actions we take in the world.
So the sefiroth, energy, or "sparks" left behind God's kenosis is us. And the path of tikkun is the recovery of sympathy and empathy plus active care for one another, and away from the vitriolic hates, personal and ethnic vengeance and self-righteousness that keep us all separate from one another.
