In the Christian sense, love is not primarily an emotion but an act of the will. When Jesus tells us to love our neighbors, he is not telling us to love them in the sense of responding to them with a cozy emotional feeling. You can as well produce a cozy emotional feeling as you can a cough or sneeze. On the contrary, he is telling us to love our neighbors in the sense of being willing to work for their well-being even if it means sacrificing our well-being to that end.
