I think the other essential part of Christianity is then extending that same forgiveness and mercy to those around us. Even our enemies. This is the especially unpopular aspect of Christianity, even within Christianity.
Though with the important caveats that _forgiveness_ is not identical to _reconciliation_, and that extending mercy to the unrepentant is dangerous and borderline incoherent ("I assure you, he will by no means get out of there before he has paid the last penny").
I've seen those concepts misunderstood, missed, or forgotten far too often in Christian circles.
