The two above verses apply to a deeply rooted ethical disease of uneducated and unbeliever people. These are pride and despair. When Man finds himself free of want and independent; he inclines to rebel, and likes to transgress the established bounds! Soon shall he become puffed up with pride, and turns away from his Lord, instead of being more and more grateful to Him.
On the contrary a believer knows that, everything comes from God. He is therefore, thankful and humble when he is free of want. On the other hand when he suffers a misfortune, he is sure that God will remove his affliction and is a sure refuge and help. Why should he then give himself up to despair and lose hope!?
He rather has his bridle cut out or broken from the hands of wisdom and knowledge, and has given up to passion, anger, caprices, fancies, and etc., that make out his natural manner and methods; and yet, all these differ from Man's instinct which he is compelled to follow.
