I've never understood why people would ask God for the lotto numbers. Surely, if he exists, he has MUCH MUCH MUCH better things to worry about than increasing your financial wealth.
Then again, I've never understood why people would pray to pass a maths test, to make their gay children straight (can't fix what ain't broken), for a new job, a new car, money, getting people out of jail who are in there cause they broke the law etc.
Surely, with the war, famine, poverty, abuse, rape, murder etc in the world - the fickle problems of a few people who aren't happy with what they have would be the least of His worries. Yet, it seems to be in the forefront of many believer's mind (NOT all, but quite a number of the more fanatically against everything else type believer (eg against gay marriage cause..."God" but happy to pray for the lotto numbers....) seem to be).
I don't believe in God, therefore I would never ask Him (or her) for that matter the Lotto numbers. And should a spiritual God type being ever present themselves to me, with the Lotto number, I'd still never follow them - a God willing to overlook child abuse etc in favour of the lotto numbers isn't worth following.
