Pride made Israel think it would recover and rebuild in its own strength. Even though God made the people of Israel a nation and gave them the land they occupied, the people put their trust in themselves rather than in him. Too often we take pride in our accomplishments, forgetting that it is God who has given us our resources and abilities. … God is not pleased with any pride or trust in ourselves because it cuts off our contact with him.
