Joy is not having what we want when we want.
And prosperity "gospel" teaching is simply untrue. God doesn't bless you if you get it just right. He is gracious to you and gives you things you don't deserve. And He is merciful...He doesn't give what we do deserve.
There are times we are in the will of God and are pressed, abandoned, and in hardship. A cursory look at the life of Paul will remind us of that. But it is His grace that sufficient for us, even in the times that are so difficult. It is disturbing that so often we think we must have missed God's call because it's hard or we are not having the "success" we were expecting.
We do not have His perspective. Only He knows what effect things are having here or in the heavenlies. We are to keep our eyes on our Jesus, be like Him, and worship Him. We are to obey Him. We are not responsible for the harvest. We are not in charge of the consequences. That would be us trying to usurp His place.
