@Dine: I agree that if you are ill it’s more challenging to be happy. I’m not even saying I could be ill myself right now and remain happy. But if I had my wish that I was living up to the person God wanted me to be, within that lies the assumption that I’m at a maturity level in my faith that allows me to feel at peace with my life (and my circumstances, including if I was ill) knowing that I’m fulfilling God’s will. In the bible, Job suffered through having boils but still had faith that he was doing a work for God although he may not have understood at the time what it was, and he was later in life doubly rewarded for the pain he endured. The point I’m trying to express here is how awesome it could be if you could be in such a terrible circumstance, such as bad health, and not understand why it is you’re in bad health, but know and have complete faith that you’re fulfilling a higher purpose, that unwavering faith would fill you with so much peace that you could endure anything. That would be such an incredible state of mind and being to have. That would bring me happiness. Would it be constant uninterrupted happiness, probably not. But I believe the peace I would feel during challenging times would make up for the time I wasn’t happy. :)
And of course, you don’t have to agree with me, but again my point was only to reflect that within my answer lies what would bring me happiness. As for health, while it wouldn’t be a specific wish I had, would be a perk if it fell within the realm of what God’s will was for me.
