That's not what Jesus said to do. You have money, and God gave it to you to share. God said sell all that you have and give it to the poor. There are many examples including the parable I Just shared about sharing our own personal money with the needy.
I agree, Christians in groups should be helping their neighbors in big huge group efforts, but the needy also need us individually. Jesus said bring them into your own personal home. Church gatherings should also be in our homes without denominational labels to separate us, meaning, the needy should be invited too.
Not every place has a big enough homeless shelter if a shelter at all, but plenty of homeless. We're going to run across homeless/needy people on our own time who are going to need our help right then, no waiting. Never pass up an opportunity to help somebody.
