Boundaries come after grace, because compassion minds the fragile places but boundaries keep them from compromising the rest. Brokenness may have legitimate origins, but left unchecked, a wound becomes infected and poisons the whole body (and subsequently, everyone around). Wounds must be attended to heal. With an unhealthy limb, the rest of the body overcompensates through manipulation, aggression, or blaming. Boundaries here are kind. Better to apply direct pressure to the wound than pretend it is well; this may get worse before better, but it is way of healing.
