Has no one here experienced God answering their prayers? I most certainly have! In many ways, too many to list. Sometimes the answer has been no, sometimes yes. But always an answer!
Has no one seen God working things together for good? Yes, I have - as I'm sure anyone else who is saved has, truthfully, even if they don't answer the question. One example is from when my Dad was sick with cancer. He had brain surgery in early July (2011). I was able to go up there for two weeks to help my Mom with my Grandma (who was heading for her 102nd b'day in November). Two weeks with one of the most precious people on earth to me, as well as time with my folks). Four months later I was back...for my grandmother's funeral. She had fallen, broken her hip, and passed from pneumonia. I spent 3 weeks there that time, helping where I could, spending time with my folks again. And then 4 months later, I was back up there. This time for my dad's funeral. How precious it is to me to know that God worked all of that, even in the midst of stress and sorrow, for me to spend time with very special loved ones whom He knew He was going to be bringing home.
Has no one noticed the protection of God? Oh, yes. More than once in my life. Sometimes looking back on situations I have to ask myself, "how in the world...?" and the only answer is God.
The provision of God? Yep. God provides. Many times above our needs.
God shutting and opening doors? Well, here you might not agree with me. I'm not a real believer in "open" or "closed" doors. I believe that God leads us to do as He desires us to do, placing those desires in us to do so (if we are right with Him, of course). And that we are to do what He leads us to do - even if we have to climb through a window, as it were...
Larry, there are times when I feel woefully inadequate in my prayers. I don't know just what to pray for or about. In such times I admit those things to God and ask that His Spirit would intercede and that God would act in accord with what's really needful in accord with His will.
When it comes to confidence in prayer, I'm confident that God hears my prayers and uses them in accord with His will. How that all works, I really don't know, but it does, just as God says.
Recently someone said to me that their faith was on the line, because they believed God was going to do something, and they were certain of it because they wanted it so badly and isn't that proof that God should do it...
My answer to this person was that God is not a slot machine. When we pray, we have to remember that He works things out for our good and His glory...not for our desires. Now, that has to be tempered with the fact that often God will lay desires/burdens upon us for which He wants us to pray and we will see the answers we want. But we have to realize that "no" and "wait" are also answers.
