Yes, God has answered prayer many times.
The year after I got the new shed, my 82 Toyota van (272 K ) began giving me serious problems. I spent $1500 in the summer (remember no pay in summer) trying to get to the bottom of them. No luck. As I was driving and conking out on the way to work in September I saw a beautiful grey van passing me by. I pointed to it and asked the Father for one just like that one. Since I did not have a cent left in the bank I told God that He knew I used my vehicles for His glory and asked Him supply me the van without depleting my bank account 1 cent.
The next day as I drove my eldest son to school I told him what I had asked God for and how much it was going to cost me (i.e. nothing). After he snickered a little I told him that God didn't have a choice in the matter. Call it presumption if you will; but I knew in my spirit what moves the hand of God. That was Wednesday.
On Saturday morning my wife said to me, "Vander, you need a reliable car to get to work; what are we going to do?" Watch God's timing here. As the words, "I don't know" crossed my lips the phone rang. It was Eleanor, a fellow teacher of the disabled from another associated school; an agnostic btw. "Vander", she said, "I hear you need a new car". :"Yes", I replied, not knowing how she knew. "Well", she said, "I have $10,000 for you and it is not a loan."
Eleanor gave me a check for that amount. Coincidentally, the accountant at work did not like her (grey) 89 Toyota van that looked like it just got off the showroom floor and sold it to me for under $10,000 even after taxes insurance and registration.
And yes, I knew in my spirit God would answer my back-to-the-wall-faith request.
Years later I encouraged Eleanor to apply for a contested and scarce severance package from the board as she was about to retire. She got the full $25,000 package. That's two and one half time what she gave me....proving among other things that you cannot outgive God.
