I used to buy lottery tickets a few times a month, sometimes more, until one day about 8 or 10 years ago it hit me - God does not want me to win big, to build a Church or two, to fund trad projects, to help my family, needy members of my chapel and others and so on. God does not want me to do those things, nope, He wants to do things His way. Period.
So since then, I have only bought a very few over the years for birthday gifts or some such thing, but for me, it simply is not in the cards - and I kinda enjoy that He prefers to do things His way. Everything will end up a whole lot better that way.
Meh. God doesn't want you to win the lottery now. It's almost as difficult to know sometimes what God doesn't want as it is to know what He does want ... beforehand. Obviously if you don't win, God didn't will for you to win. But it's hard to know beforehand what God does or does not want.
Wasn't there some gentleman who won the lottery to help build Padre Pio's hospital? I think Padre Pio told him to pray to some saint who was also patron saint of lotteries.
