Your illness does not spoil the pleasure of Divine bounties, on the contrary, it causes them to be experienced and increases them. For if something is continuous, it loses its effect. The people of reality even say that "Things are known through their opposites." For example, if there was no darkness, light would not be known and would contain no pleasure. If there was no cold, heat could not be comprehended. If there was no hunger, food would afford no pleasure. If there was no thirst of the stomach, there would be no pleasure in drinking water. If there was no sickness, no pleasure would be had from good health.
The All-Wise Creator's decking out man with truly numerous members and faculties, to the extent that he may experience and recognize the innumerable varieties of bounties in the universe, shows that He wants to make man aware of every sort of His bounty and to acquaint him with them and to impel man to offer constant thanks. Since this is so, He will give illness, sickness, and suffering, the same as He bestows good health and well-being. I ask you: "If there had not been this illness in your head or in your hand or stomach, would you have perceived the pleasurable and enjoyable Divine bounty of the good health of your head, hand or stomach, and offered thanks? For sure, it is not offering thanks for it, you would not have even thought of it! You would have unconsciously spent that good health on heedlessness, and perhaps even on dissipation.
