The lottery is not only a bad idea from a statistical standpoint; it goes against some fundamental biblical principles regarding money.
First of all, we have to understand that God owns everything and we are merely MANAGERS of His stuff. (By the way, did you know the Bible talks more about money and possessions than prayer? So, God is very interested in how we handle our money.)
Let’s say you’re the general manager of a company. You’re in charge of handling the assets of this company responsibly. The owner calls a meeting with you to discover you’ve been spending his money on lottery tickets.
You respond with “well, you can’t win if you don’t play” and “somebody’s gotta win”. Sounds ridiculous, right? How do you think owner would react? Do you think he’d give you more to manage? I doubt it. In fact, you’d probably get fired.
God wants to bless you with more. But if you’re not currently managing His assets well, the door of blessing may be closed. Remember, he who is responsible with little will be given more. Don’t waste money on the lottery, then wonder why you’re not prospering.
Secondly, the lottery oppresses the poor. The vast majority of lottery tickets are sold in poor, uneducated neighborhoods. The Consumerist recently stated in 2009 folks making $13k a year (poverty level) or less spent 9% of their income on the lottery.
As Christians, we’re called to have a heart for the poor. However, when you play the lottery, you’re supporting a government program that preys on poor people. Famous pastor/author, John Piper, posted this on his blog: “So, if you win (the lottery), don’t tithe your winnings to our church. Christ does not build his church on the backs of the poor”
