I have better things to do with my money than gamble or play the lottery, but the basis of my conclusion is that I can give it to the church, provide for my family, or invest in retriement. I am not so sure about the reasoning of getting something for nothing in the same light as someone being supported by someone else who will not work.
In the 1920's, our church minutes record an incident where a member was disfellowshipped for investing in the stock market, or for the mindset of the day, getting something for nothing. Today, how many of us do not invest in stocks, bonds and mutual funds for retirement. We do not consider that getting something for nothing today. We are putting at risk funds to make a profit, because with a savings account or CD today, one would starve to death.
So, what gives us the right to say the stock market is ok, and the lottery ticket is not. Fifty years ago both were wrong. In fact, one could say that interest on a savings account is something for nothing. If you are investing your retirement in stocks or bonds, what makes that different than the lottery ticket? What makes the line between the stock market and lottery ticket the right standard compared to the standard fifty years ago?
I do not buy lottery tickets or gamble, but we need to be honest about why. If we base it on Scripture, we need to have a valid reason for saying the stock market is ok and lottery tickets are not in based on the Bible.
Common sense has to come into play somewhere. If you are depriving your family of support, or you are addicted to gambling devices, you have no business playing the games.
To answer the op, and this is an op of pure opinion, I would say a Pastor hs better things to talk about than buying lottery tickets, like getting people off the pews and serving the Lord. My guess is that the Pastor is invested in stocks somehow.
