Some people do advocate taking this verse alone, literally, without other context. Think about it. You have a limited budget, but you want a 4 or 5 bedroom house when you have a 3. Even though your two and a half kids are about to go off to college, it would be really cool to have that extra room for stuff, as you have accumulated a lot, and its so hard to cull through it. Anyway, if you have more room, you can get more stuff - and stuff is nice! So you ask, believing on this promise. Should God give it to you? Maybe He would not be a very wise and loving Father if He did. Then, He wouldn’t be Himself. So this must not be the answer.
Based on this verse, a popular theology among some Protestant groups is “Name it and Claim it.” Though I did not call it that, I sort of believed it (it seemed Biblical!). Especially in the case of my marraige - certainly God wanted that to be better, forever. Certainly that was His will, since He hates divorce. It seemed safe to believe that I woudl receive this answer to prayer, despite all evidence to the contrary. I saw the evidence, but I believed in God to do a miracle, and my role was to do my best and wait for Him to act.
When I was faced with divorce, I wondered if I should not drag it out with a “no divorce” case so God could have more time to do the miracle I had been waiting for in good faith. A good lawyer advised against this. So I ask a holy and strict priest, telling him this lawyer’s advice, and telling him that if I took the advice (basically it was divorce him back), I felt I would be giving up on God, whom I had been waiting on all these years. He told me that “God does miracles, but He never tells us to expect one.”
So, this is the truth.
