Never saw it that way before. Not that I think humans should pray for mercy or favor in any case. When so many others who have a more humble, honorable spirit go hungry or suffer in other ways, it's sort of selfish to ask for favors they aren't getting. Of course that doesn't stop me from praying for mercy and favor for others. I want to smack the televangelists that tell people to pray for wealth, cars, and prestige though. We should probably spend more time thanking Him for what mercy and favor He's already given us.
I have been taught that it is always improper to pray for something personal, unless it includes all who are in the same circumstances. And you are to still exclude yourself, so you can ask for the right thing. If you are deserving, you will be included in the answer. It is far better not to pray for any earthly things at all. Who knows what the purpose and instruction to be found in the particular circumstances are? And why question the Will of God? If this Goy prays at all, it is for revelation, and for all of man, never for myself. I make it short and sweet, for no one is impressed, least of all God. I do thanksgiving prayers, though. There is no reason not to celebrate the gifts I have received. I have everything a man could ask for; and it does not include position, material goods, or any degree of wealth. They are all transient stumbling blocks that have been cleared from my path. I have health, good food, clean water, a warm home, love, inner peace, and God to contemplate all day long. What else is there that is of any value to anyone?
