“For Demas hath forsaken me, having loved this present world, and is departed to Thessalonica”; that is, having loved his own ease and security from danger, he has chosen rather to live luxuriously at home, than to suffer hardships with me, and share my present danger. He has blamed him alone, not for the sake of blaming him, but to confirm us, that we may not be effeminate in declining toils and dangers, for this is, “having loved this present world.” At the same time he wishes to draw his disciple to him.
