Most people nowadays don't care about sin, what they want is money and satisfaction because with money you can solve every problem in the world and satisfaction make you know why you need to live long.
People knows about sin but they don't thinks much about that. They thinks that playing gambling is like the other activity that they do and if they can control themselves in gambling, they will not face any problems at all. That will be danger if they lose control, especially many people already lose it so they will learn hard about self control before something bad happens to them. Playing gambling needs many things to protects them from the problems.
Now, Im not here to preach. We dont go telling people what to believe. They know whats right, whats wrong - way better than anyone else, believe me. Some folks will figure it out, change things up, others... well, we'll see. Its their path. We dont judge, thats not our place.
If you gamble, do it the smart way. Its not just about faith, its good business sense. Set limits, be strategic. Thats the winner mentality. It shows responsibility, and yeah, maybe you're working with your beliefs, not against them. Thats a win-win in my book, a huge win.
Many people already tempts to playing gambling and makes them lose self control from gambling. It's why we must always remember that gambling is just one of many activities that we can do to have fun. We can do the other activities and not using gambling to have fun and that will be safe for us because we can avoids lose much money and gets addicted to gambling.
Religion tells people about the bad and the good but human have their own selection and they will responsibly with what they takes. They must knows that playing gambling can gives problems so they will prevents that problems occurs to them.
