The pursuit of happiness is in the Bill of Rights. Yet, happiness can be destroyed by harboring hatred towards another.
Esther 5:13, “Yet all this benefits me nothing as long as I see Mordecai the Jew sitting at the king’s gate.”
In the verses before this Haman recounted the riches, his ten sons, his promotions, his position, the famous people he dined with; and none of it brought happiness.
No one can make you happy or keep you happy. No item will bring happiness forever. Happiness is found by keeping our hearts pure before God. He gives, not only happiness, but unending joy.
