Love has words of encouragement for the lonely, the down-trodden, and others who deserve and need uplifting. But some are ever tooting their own horns. When a windbag preacher boasts that were it not for his efforts the whole brotherhood of Christ would be immersed in apostasy, one cannot but be reminded of this descriptive. Love is not puffed up. The original language here denotes one who is inflated with a sense of personal pride.
Pride is unreasonable self-esteem, generally accompanied by insolence and rude treatment of others.
Love is characterized by genuine humility. Love does not behave itself unseemly. It encompasses all sorts of evil activity, bad manners, and brutal rudeness. Love doesn't deliberately seek to be offensive. Love operates with determined politeness.
