So show me the scripture. So far no one has given a single scripture that shows that gambling is sin.
Here is one.
1 John 2:15-16
Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.
For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
From my understanding the difference between gaming, gambling and occupational risk taking are the issues of the heart, including motive and intent.
Gaming, for the sake of the pleasure of company, the thrill of risk and hopefully winning can be done without much of an investment. I have played cards and dice for such high stakes as chips (plastic), beans, toothpicks and matches. When the game was over, all the fun was had, but no one's bills went unpaid, no one went hungry or into debt for the fun of the game. The thrill of the risk and chance was superficial.
Gambling has the same fun, but with much higher consequences, whether winning or losing. Losing produces loss of resources, but winning provides an emotional high that is addictive to many personality types and is more dangerous than losing.
Occupational risk taking, as in farming and ranching, according to many of the same, that I have pastored over many years and according to the Bible, is more of an act of faith in God's providence than it is gambling.
Is gambling a sin? I doubt that we can find a verse that says in some measure, Thou shalt not gamble, but the issue that troubles my heart when it comes to gambling is two fold, 1. As the above verses speak, where is our love focused. Do we as believers take our delight in the same things that the lost people of the world find so extremely stimulating. In my life if have been to Vegas, once and in three or four other casinos with friends. In each case I was awestruck with the reality that people were there for the hope of gain, no one seemed to be having fun. Maybe I missed the spots where they were, but in reality, I'm quite confident that I saw a good sampling. Will anyone go to hell because of gambling, whether mine or theirs, I doubt it. But, I am always asked in my spirit, who do you love?
2. Simply put, our money is our life and if we gamble it on the turn of a card, the spin of a wheel or whatever, we are unfaithful stewards, indeed. We trade our time on the job for money and we trade that money for goods or services that we need and perhaps to share a blessing with others. But remember, it is our life, converted into money we are spending. Spend it wisely.
As a child of God, I believe we are called to a life of holiness, becoming more and more Christ-like as we grow in Him. Therefore, it is not my goal and hopefully yours as well to see how much like the world I can be and still serve my Lord, but rather to see how much more I can serve Him and honor Him each day.
I have never felt the presence of the Lord in a casino, even though I am sure a lot of praying was going on.
