Romans 12:15

Rejoice with them that do rejoice. — The feeling of sympathy is perhaps more under the control of the will than might be supposed. It becomes so, however, not so much by isolated efforts as by a conscious direction given to the whole life. The injunction in this verse is one of those that have been perhaps most fully carried out in modern times. It has entered into the social code, and belongs as much to the gentleman as the Christian. The danger, therefore, is that the expression of sympathy should be unreal and insincere. This will be prevented by the presence of the Christian motive.
