Gambling goes against Christian teaching
To give a little and get a lot is the way of the worldly man (Prov 21:25-26). But to give a lot without any thought of return is to be the way of the Christian (Acts 20:35). The two ways of thinking are against each other. To love God is to want to give to others, to love money is to want to get from others. You cannot do both at the same time (Mt 6:24).
