We all suffer the slings and arrows that are found in this fallen world. Those christians with girlfriends or wives have social problems as well, just different kinds of problems than you would have. Its the same thing as the foot, in the body of Christ, not being jealous of the hand, or the mouth. You have your own strengths and weaknesses. Jealousy of others joys found in life is not wise, for you are focusing on the good things you see with them and cannot see the downsides they live with. The grass is NOT greener on the other side, coveting anything our brothers and sisters have, only shows our lack of love in wanting them to have only the same as us or less.
