I don’t know if this is theologically accurate or not, but I wonder sometimes if God doesn’t give us our requests if only for the simple reason that we never asked for them in the first place. I think of James 4:2, which says, “You do not have because you do not ask God.”
Maybe that’s taking the verse out of context, but I think the message is to ASK. Pray for healing. Pray for a miracle. Pray for what seems impossible. Pray for what only God could do so that when the request is granted, all you can do is to thank God for it.
And keep praying. Don’t give up. Be like that annoying widow who finally got what she wanted because she persisted. And I say annoying because the judge was so annoyed that he finally gave in.
That’s all. Just keep praying.
