I have not seen any case of gambling addiction seen from the angle of being spiritual motivated. It's just like other types of addiction like drugs, alcohol and others. It is best viewed from from the angle of poor mentality than any other thing. It is poor mentality that leads to greed, desperation and all negative things that manifest as gambling addiction.
People are so dramatic with their mentality of saying and believing that gambling or it's addiction is a spiritual attack.I don't understand why people would conceptualize an opinion and overwhelm it to themselves in such awkward manner.It certainly doesn't centers any need to give biblical significant explanations and alternate descriptions about gambling as a spiritual attack.
From a level of truth,gambling puts somebody's money at a great risk,that notwithstanding too,the reasonable triggers that emerged into gambling should be given attention too.Initially,the behaviors from gambling addiction is discouraged both in biblical terms and there needs to be a balance with the way people addresses it.
