What I think is important here, and what is seems many in the comments below are missing out on, is that Jesus says that it is hard, not impossible. Giving all your money away will not suddenly make you a good person, just as never having had money does not mean you are a good person. Jesus charged his followers with living lives of self sacrifice on the behalf of others in all aspects. Annias and saphira did not drop dead because they did not give up their goods but because they lied about it. I know many Christians who have done very well financially and are the most generous people I know. I also know some who are very stingy and uncompassionate with their money. The fact is, those who have more, have more that they have to give up. Those who have less, have less to give up. Each, however, is charged to live in the same manner.

God asks us to give freely and abundantly as he does. This is not forced upon us, though. There is no forcing someone to obey certian things in Christianity. Jesus says that is we love him, we will keep his commands. Those who choose not to keep his commands are demonstrating a greater love for whatever the opposite is at that time. Love involves choice, though. It is not a socialists ideology enforced upon every person. A perfect christian community would look socialistic but would arrive there through the perfect love of one’s neighbors. Unfortunately, we do not live in a world of perfect Christians whose every decision is fuled by the love of others. I would also suspect that many, if not most on here, would have a problem with Christians forcing upon others their beliefs so as to attempt to achieve this. That, however, is what would be happening if someone forced upon others a socialists society without their consent.
