"After this manner therefore pray ye:
Our Father which art in heaven, Hallowed be thy name.
Thy kingdom come. Thy will be done in earth, as it is in heaven.
Give us this day our daily bread.
And forgive us our debts, as we forgive our debtors.
And lead us not into temptation, but deliver us from evil:
For thine is the kingdom, and the power, and the glory, for ever.
While the sign brings to my mind several questions, and I thought first to list my questions for you to answer; I think I will make that jump and answer them myself today. The exemplary prayer Jesus used to teach His disciples how to pray had a mere 66 words in English; 73 in the original Greek, so wordiness can not be important in prayer. The Widow who gave small change in Jesus' church (The story of the Widow's Mite in Mark 12:42) certainly was noticed by Jesus, making it a safe deduction that prayer answers are not in the nickles and dimes.
If someone is praying for a million dollars, then they need to get off their knees and get a job. That's where money comes from. And, Jesus sent Peter fishing to pay the taxes as an example of the importance of both honoring obligations and hard work. Matthew 17:27 Incidentally, Peter didn't pull any more than he needed for the tax bill out of the fish's mouth. There wasn't enough left for all the other things he had been wishing for lately.
But, lastly and uppermost in my mind, why would a church (or a Christian) be praying for a million dollars? They need only pray to reach the lost and God will meet the need. Perhaps God knows the cost of our daily bread. Do we really need to give him the itemized bill? Surely not. Just ask God for what you need. He doesn't need a calculator and He can do the Math Himself.
Besides, if your heart is in your prayer, then every part of your life will be connected to God, not just your pocketbook. If you are looking for God, whether you use the example of a model prayer or just speak from your own heart, your prayer can impact heaven and earth.
If a son shall ask bread of any of you that is a father, will he give him a stone? or if he ask a fish, will he for a fish give him a serpent? Or if he shall ask an egg, will he offer him a scorpion? If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him? Luke 11:11-13
