It's really a form of self-righteousness, because it is pride. What is this business of hinging your faith on the answer ? It's like," Show me ! I'll believe it when I see it! But, that's not the way faith works. You can't make the answer conditional to your service for God...you ought to serve Him regarless. It may even encourage some poor people who have worse problems than you to go ahead and serve the Lord, and not be ashamed regarless of handicaps. JOB is a good example; he lost everything ...his family, his fortune and finally his health. But, it didn't matter if God allowed him to die, he'd < still keep on trusting Him !
You can't only be God's fair-weather friend, you have to keep on serving Him even when everything goes wrong. And, if you're a Christian alot of things go wrong as, "many are the afflictions of the righteous". (Ps34:19) What's your healing got to do with faith and obediance ? Nothing ! Although, your faith and obediance have alot to do with your healing. As long as it is possible for you to keep on serving God, you've got to keep on serving Him whether He sees fit to heal you or not !
A lot of people just want to use God. People with that self-righteous attitude are saying," if I were God, I'd do things better." But, that's because they don't understand what God is doing or why, and they will never understand until they have faith to trust Him that He knows best.
People who live within God's Gates of Faith can survive anything, even death ! Like JOB," though He slay me, yet will I trust in Him !" (Job13:15) So, if you've got real faith you'll keep going for God even if it kills you ! And it will kill your pride, your self, and all that self-righteousness. Keep going for God ! Keep believing and obeying no matter what happens.
So, which will it be for you ? Are you going to quit over a few trials, or are you going to keep going for God even if the Devil is allowed to kill you as a witness to your faith and obediance to the Lord ? God can keep you, but if not don't quit !
