Romans 12:15

"Rejoice with them that do rejoice, and weep with them that weep." Since it is possible to bless and not to curse, and yet not to do this out of love, he wishes us to be penetrated with the warmth of friendship throughout. And this is why he goes on in these words, that we are not only to bless, but even feel compassion for their pains and sufferings, whenever we happen to see them fallen into trouble. Yes, it will be said, but to join in the sorrows of mourners one can see why he ordered them, but why ever did he command them the other thing, when it is no such great matter? Aye, but that requires more of a high Christian temper, to rejoice with them that do rejoice, than to weep with them that weep. For this nature itself fulfils perfectly: and there is none so hard-hearted as not to weep over him that is in calamity: but the other requires a very noble soul, so as not only to keep from envying, but even to feel pleasure with the person who is in esteem. And this is why he placed it first. For there is nothing that ties love so firmly as sharing both joy and pain one with another. Do not then, because thou art far from difficulties thyself, remain aloof from sympathizing too. For when thy neighbor is ill-treated, thou oughtest to make the calamity thine own. Take share then in his tears, that thou mayest lighten his low spirits. Take share in his joy, that thou mayest make the joy strike deep root, and fix the love firmly, and be of service to thyself rather than to him in so doing, by thy weeping rendering thyself merciful, and by thy feeling his pleasure, purging thyself of envy and grudging. And let me draw your attention to Paul's considerateness. For he does not say, Put an end to the calamity, lest thou shouldest say in many cases that it is impossible: but he has enjoined the easier task, and that which thou hast in thy power. For even if thou art not able to remove the evil, yet contribute tears, and thou wilt take the worst half away. And if thou be not able to increase a man's prosperity, contribute joy, and thou wilt have made a great addition to it. Therefore it is not abstaining from envy only, but what is a much greater thing that he exhorts us to, namely, joining in the pleasure. For this is a much greater thing than not envying.
