Love is not jealous. Jealousy is a feeling of displeasure caused by the prosperity of another, coupled with a desire to wrest the advantage from the person who is the object of one's envy. The loving person will rejoice at the success of others. Jealousy has destroyed many a home and church. Love vaunts not itself.
Genuine love is selfless.
It seeks to extol the virtues of others. 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.
