That is how the tradition I have been exposed to seems to approach teaching on prayer.  Jesus said ask anything in my name and I will do it for you.  One of the apostolic letters says you have not because you ask not, and you ask and have not because you ask amiss, that you may consume it upon your lusts.  Holding these and other verses in balance leads to we should always try to make sure we pray in the will of God because God is glorified in giving us what we ask for, and we must try to avoid praying this way or that way or with this motive or that, we must keep our motives pure.  A law-bound, legalistic, nit-picking approach to prayer.

If we accept that there is humour in the Bible (do we?) and that we first grow up when we have our first real laugh at ourselves (so humility and humour go together, by that reasoning), it would be more reasonable and humble to say, rather than making all these books and teachings out of it, that yes, sure we can pray, but if God doesn’t like what we are asking for He isn’t going to give it to us.  If we love Him and believe He loves us and wants the best for us and those around us, accepting that, without needing to make and understand and live by theses, should make us happy and secure, shouldn’t it?

The teaching that God supplies our needs and also some of our wants is good.  It is enough.
