When I hear it, I envision some longsuffering soul who is biting his/her lip while encountering soul-devastating treatment and never speaking truth, never suggesting to the unconditional love recepient that their behavior or attitude is harmful, etc.
Well... keep in mind that I did say, that just because one loves unconditionally, it does not mean that one accepts all behaviors unconditionally.
I would never call Jesus a push over... even though he went quietly toward that cross....
