What do you do to share you wealth (spiritually, financially, religiously, psychologically, physiologically) with others?
The way I look at it is that sharing wealth with others is part of the communist bible, especially where that other owns a smart phone, and / or a TV. If you're rich enough to afford such things, and who isn't, then what you want expecting "my" money?
The only obligation on the Christian is to promote the gospel, and to that end service should be devoted. The question is a bit like asking Lot, living in Sodom, what he did to share his wealth with the inhabitants thereof? Considering how the inhabitants treated his visting angels, who can blame him if he spent most of his wealth on closed circuit CCTV, and protective walls and gates, and a sizeable security detail?
We must be careful not to fall victim to scammers, whether looking like religious who demand unscriptural tithes, or charities who frequently only donate a fraction of their income to charitable causes (and are sometimes bogus anyway) or looking like beggars who often earn more than those who do an honest day's work.
I think the question presupposes that someone is wealthy. Yet most are not, comparatively. Charity on any substantial scale is always a matter for the rich, not the average person. The issue is more about doing good when the opportunity arises out of the little that one has, and without any moral obligation to participate in social communism in an irrelegious society.
