Present in Joy and Sorrow

If we cannot respond to a person's joy and delight as we can to his pain, we have not recognized him as a person.  It means being as present to the celebrants at Cana's wedding feast as to the mourners at Lazarus' funeral.  Had Jesus only understood sorrow or had he responded only to despair, he would have been virtuous, kind and concerned but less human than we need him to be.
